Description of problem:
I use $startx to start kde from init level 3 on the latest rawhide. After today's updates, (I suspect kdelibs in particular), kde starts, but when parsing the first few of it's components on the splashscreen, a 'crash popup' shows behind the splash which is a dump of kbuildsycoca. The dump will be attached.
I tried this two ways:
1) As a new user with no $HOME/.kde directory
- This crashed many times rather than once, and couldn't complete kde
2) As an old user with a .kde dir that was working fine before today's updates.
- This crashed once, and after I saved and closed the crash popup,
kde 'appears' to run ok.
---- Kbuildsycoca crash popup contents ------
I'll submit as attachment after the initial report.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install kdelibs-3.4.0-3 from 08Apr05 rawhide
2. start kde using /usr/bin/startx from lvl 3 with or without a .kde directory.
3. note any kbuildsycoca popups/crashes
Actual Results: Kde either crashed if no .kde directory with multiple popups, or if .kde exists and was ok before, then only a single kbuildsycoca popup appeared but kde functioned.
Expected Results: Normal kde startup, no popups, no crashes.
1) All rawhide up to 08Apr05.
2) Latest -Bk kernel (2.6.12-bk2)

This was the kbuildsycoca dump from the popup during kde startup.
If you're starting kde without a .kde directory, then you'll get a large number
of these dumps. All appear to be similar, but are happening on various events.
And finally: It took me awhile to find the prior version of kdelibs to test
reversion. The result was this:
Reverted to kdelibs-3.4.0-2, (and -devel) and the kbuildsycoca dumps are gone in
both .kde and non .kde directories. It works fine.
I was also concerned that I'd recently installed glibc without restarting kde,
but this seems to be a kdelibs situation.
could you please attach the /etc/xdg/menus/applications.menu.
does it work if you just remove the file /etc/xdg/menus/kde-applications.menu?

As asked for "applications.menu".
Removing it didn't cause the problem to go away. Is there a -debuginfo for that
version of kdelibs? If not, I suppose I can try a rpmbuild from the .src.rpm
and use that. I know my crash-log isn't too informative without symbols.
I can confirm the same crash with -3 version.
it's strange, are you sure that you have removed the
it works for me after removing this file!
if you overwrite /etc/xdg/menus/kde-applications.menu with
/etc/xdg/menus/applications.menu, does it still crash ?
cp -f /etc/xdg/menus/applications.menu /etc/xdg/menus/kde-applications.menu
My mistake ;) ::
I'd made a backup xdg directory and removed it from there somehow. Yes, it works
fine if I get rid of that file. Thanks.
Meanwhile, I'm building the -debug*.rpm for kdelibs from source. If there's any
other tests you'd like me to run, just say the word.
please don't use the kdelibs-3.4.0-3 in the rawhide, it's broken because of new
gcc-4.0.0-0.40, which miscompiled kde/qt :(
for more infos #154294
it's already fixed in kdelibs-3.4.0-4, which is available in rawhide.
