[SOLVED]:plasma crashes at startup

consumptivas · 2018-05-19 09:24:45

Hello,

Yesterday, I updated my system and, maybe nothing to do, but on my home hard drive, I had no more space available. So I free disk space and rebooted.After restarted, plasmashell has crashed. I See black screen, but mouse, other programs, multiple desktops, dolphin, etc--all worked fine. Just no menu bar, no desktop wallpaper. Rebooted, logged in, saw the wallpaper, then it crashed again.

I am unable to start plasmashell
Here is the output :

Any idea ?

Post a backtrace, terminal output is useless for crashes.

No backtrace, gdb return me 'Reading symbols from plasmashell...(no debugging symbols found)...done.'

so backtrace in gdb return nothing...

I ran :

gdb --args plasmashell --nofork 2>&1 | tee plasmashell.dbg

What am I doing wrong ? how do I get backtrace ?

EDIT : 'run' command in gdb did nothing for mysterious reason. Rebooted and finally get BT.

I thought it was a widget problem but I finally solved the problem by cleaning the cache :

$ rm ~/.config/Trolltech.conf
$ kbuildsycoca5 --noincremental
$ kbuildsycoca4 --noincremental
$ rm -rf ~/.cache/*
