Re: [trinity-users] kbuildsycoca hangs --- no login

High all, now again an active post from me, obviously with a problem report. Basic info: I'm running OpenSuse 13.1 with TDE 3.5.13.2-3.oss131.opt.x86-64 Because somehow I couldn't get TDE's display manager to run, the one in use is KDE4's, kdm-4.11.9-111.1.x86_64. Today I was hinted to quassel for an IRC client, checked the Suse repos, found and installed it. The installer reported as the only unresolved dependency for quassel-mono (monolithic/stand-alone package, nothing to do with the Mono runtime) the evenly provided quassel-base package, which I confirmed to also install. During the installation process, kicker crashed and when it was attempted to be respawned, the CPU load increased to 50% overall (2core HT current i5-M). The load was partially from kicker, partially from kbuildsycoca. After killing both, I tried to manually run kicker again, but the same happened, just with only one thread worth of CPU load occupied. "init 3" (I know it's not the same with systemd, but...) didn't even kill kbuildsycoca. After manually killing it, I switched back to RL 5, and I got the greeter screen (background), but no entry fields or menus or whatever --- the CPU load was again at 25%. After uninstalling the two quassel packages, I switched to RL 3 and back to 5 again, but there was no difference. I rebooted the box, and was prompted with the usual greeter, including the user/passwd fields etc., entered the password and the same happened again: 25% CPU load, in kbuildsycoca. I attached gdb to it, without really knowing what I should look for, but maybe one of you can read some valuable information from the backtrace: (gdb) bt #0 0x00007f462f734980 in __read_nocancel () from /lib64/libc.so.6 #1 0x00007f462f6d0338 in __GI__IO_file_underflow () from /lib64/libc.so.6 #2 0x00007f462f6cf678 in __GI__IO_file_xsgetn () from /lib64/libc.so.6 #3 0x00007f462f6c5418 in fread () from /lib64/libc.so.6 #4 0x00007f46319525f7 in QFile::readBlock(char*, unsigned long) () from /usr/lib64/libqt-mt.so.3 #5 0x00007f463195c6df in QDataStream::operator>>(int&) () from /usr/lib64/libqt-mt.so.3 #6 0x00007f463265e1c8 in KSycoca::kfsstnd_prefixes() () from /opt/trinity/lib64/libkdecore.so.4 #7 0x00007f463265e3c8 in KSycoca::language() () from /opt/trinity/lib64/libkdecore.so.4 #8 0x00007f462d0aa20a in kdemain () from /opt/trinity/lib64/libkdeinit_kbuildsycoca.so #9 0x00000000004090ff in ??
