Bug#807379: kde-full: kdeinit, plasmashell crashes connected with libthread_db.so.1
Package: kde-full
Version: 5:90
Severity: grave
Justification: causes non-serious data loss
I've got numerous crasches connected with libthread_db.so.1. The most
problematic are crashes of kdeinit. When I suspend to RAM and resume, I should
get password prompt screen. Instead of that I usually get the screen with
active windows without title bars (looks like kwin not working). Visible
windows are functional, one can watch and modify its content it is also a
security thread.
I have to restart KDE to get system usable (going to init 3 and then init 5).
There is more crashing apps. Kwin stops quite frequently (windows without
titlebars, etc.) but it can be started manually.
I observe also crashes of other KDE apps like Dolpin, Konsole all connected
with libthread_db.so.1.
The crashes of kwin are usually connected with changing monitor setup. I work
with laptop and two external monitors at work (connected to DisplayPort and
D-SUB). When i connect or disconnect external monitors kwin usually crashes.
