help to troubleshoot crash




Hi all,

Please would you help me troubleshoot this. It occurred on Fedora 26 when attempting to login using the KDM window manager.  What info should I be looking for?

Note, the crash is similar to what a gaupol user is seeing https://github.com/otsaloma/gaupol/issues/47

And https://bugzilla.redhat.com/show_bug.cgi?id=1395968 ??

Thanks

Rick
