Gentooer here, too! =:^) But I'm running a generally ~amd64 system with
the gentoo/kde overlay and currently the latest kde release, 4.8.0.
FWIW, I also ran the 4.8 prereleases, betas 1 and 2 and rcs 1 and 2
(versions 4.7.80, 4.7.90, 4.7.95 and 4.7.98, IIRC). Similarly, I'm
running a direct Linus upstream git kernel, currently 3.3.0-rc2-172-
g23703f8, gcc-4.6.2, binutils-22.214.171.124.1, portage-2.2.0_alpha85,
grub-1.99, live-git openrc-9999 updated every few days, etc, all of which
are either package.keyworded ** or package.unmasked in ordered to merge
them. So I'm definitely running somewhat ahead of many of your packages,
FWIW, I got fed up with akonadi, however, and unmerged all of kdepim in
ordered to be able to unmerge it. With it unmerged, I was able to set
USE=-semantic-desktop, etc, so I have all that turnakonadied off as
well. You'd be AMAZED at how much faster kde runs now! I know I was --
it was like an MSWormOS user finding out how much either the malware or
the malware scanners had been slowing him down or like getting a free
half-gigahertz or another couple cores CPU upgrade! I was /reasonably/
happy with kde4 before, but now I'm MUCH happier with it! =:^)
However, kmail, akregator, korganizer, knode, kaddressbook, etc, are part
of kdepim and thus pull in akonadi, so if you use any of them you'll have
to switch to something else if you decide to go the no-akonadi and
possibly no-semantic-desktop route, as I did. FWIW, I ran kmail and
akregator, but switched to the gtk-based claws-mail for both. Given the
decade-plus of mail archive I have, the conversion wasn't fun, but it
wasn't much worse than the conversion from pre-akonadi kmail1 as found in
kdepim-4.4, to akonadi-based kmail2 as found in kdepim 4.6+.
I haven't seen that error, but since I switched to claws-mail and unmerged
all kdepim and akonadi before kde 4.7.1 (I was off of kmail for 4.7.0 but
was still using akregator so couldn't unmerge akonadi until I could
switch off akregator as well), if it's an akonadi issue, I'd not expect
What is akonadi? It's the common database middleware that all of kdepim
is gradually converting to use. It can actually use one of several
database backends, including mysql (the original default) and sqlite (the
newer default). The first kdepim app converted was kaddressbook, with
kdepim 4.4. kmail was next, but that was a major project, so there was
no kdepim 4.5, and kdepim 4.6 was released with the converted kmail2, but
not considered stable or released in version sync with the rest of kde
sc. With 4.7, kdepim synced with the rest of kde sc again, but on gentoo,
it remains possible to run current kde (thru 4.8.0 at least) with the old
kdepim 4.4.x and thus the old unakonadified kmail, since the akonadified
kmail2 is still problematic for many people.
But upstream kde/kdepim are no longer updating the older 4.4.x version,
so it'll gradually get more and more difficult to keep it working with
current kde, until various distros decide to drop it. gentoo/kde is
keeping the old kdepim 4.4 for use with kde 4.8, only because they've
seen no major issues with it that they hadn't already worked thru for
4.7, but eventually, there will be issues and gentoo/kde isn't going to
put a lot more effort into fixing them, so whenever they come up, you can
expect gentoo to drop the old kdepim 4.4 series.
Meanwhile, with kmail2 as it's found in kdepim 4.6+, it's now akonadi
that does all the mail fetches, etc. Presumably, it's one of those jobs
that's failing, leaving the dialog box behind. Of course, that's
assuming that everybody's guess about what that box belongs to, akonadi,
Personally, given that I've already stated that I switched off of kmail
and dumped all of kdepim as I simply didn't find the akonadified version
worth the trouble any more, it should be obvious that's what I
recommend. I also expect you'll be quite pleasantly surprised at how
much faster kde is if you kill akonadi and friends, especially if you
take the opportunity to kill semantic-desktop at the same time.
And I can also say that I've been very happy with claws-mail as a
replacement, altho the conversion wasn't particularly easy.
But of course, all that is up to you. If despite that dialog, you're
finding that the akonadified kmail, etc, is working well for you, as it
surely will for some people, by all means, go ahead and keep using it, if
you wish. But if you've thought about trying something else out, now's
the time to do it.
