Answer below, but first... Please turn off the HTML when posting to
mailing lists. It's controversial as a lot of folks consider it a
potential malware/spyware vector (webbugs, among other things) and spam
indicator and thus chose to use clients without HTML parsing enabled. On
many of these the HTML mail portion simply looks ugly. As it's often the
old-time regulars that know a lot about a subject that have this
viewpoint and they are often on enough lists that they are picking and
choosing what to reply to already, frustrating or offending the people
you want a good answer from isn't a particularly good idea, as they
killfile such messages or simply ignore them and move on to others
without the problem in the first place.
To answer the question, kde uses text-based configuration files (instead
of a binary-based registry) for ease of editing, but keeps a runtime
binary cache called the Kde SYstem COnfig CAche, aka ksycoca, for
responsiveness. There's two apps involved in its maintenance, kde
daemon, aka kded, that notifies running apps when ksycoca changes at
runtime, and kbuildsycoca, that normally runs at startup to collect the
current config and update the ksycoca binary cache to the latest config.
If for some reason a configuration change isn't detected properly at
runtime, usually running kbuildsycoca manually fixes it. Note that for
kde4, it's actually kbuildsycoca4, and that normally it does a fast but
not as thorough "incremental only" scan. To do the really thorough scan,
use the --noincremental option.
So try running...
... and see if that helps. Of course you can try it without
--noincremental first if you like and it'll probably work, but using that
option is normally recommended just in case. Note that if you run it in
a konsole, you may well get a bunch of complaints about minor errors in
*.desktop files, etc, but these are for developers and as a user you can
generally ignore them.
As you're dealing with icons you /may/ need to delete the icon cache AND
run kbuildsycoca4, but that should do it without a restart. If dolphin
(or plasma or konqueror or whatever, you didn't mention what app) doesn't
update at that point, consider filing a bug, as it should.
