Description Jeff Fitzmaurice 2015-12-11 18:54:19 UTC

Application: plasmashell (5.4.3)

Qt Version: 5.5.1
Operating System: Linux 4.2.6-201.fc22.x86_64 x86_64
Distribution: "Fedora release 22 (Twenty Two)"

-- Information about the crash:
- What I was doing when the application crashed: I pretty much now just have to boot into Plasma and it crashes.  I have also been having Firefox Crashing, but not sure if that is related.

So, whenever I boot into Plasma, Plasma crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Bus error
Using host libthread_db library "/lib64/libthread_db.so.1".

There at the end, I was having a total break down of KDE in Fedora 22.  So, I wiped the drives and did a clean install to Fedora 23.  I'm not sure what the problem was.  I think it was some data corruption.  It seemed to stem from Akonadi.  From Gnome I couldn't access anything dependant upon MYSQL via Akonadi.

Comment 2 Harald Sitter 2015-12-14 11:26:20 UTC

Actually most likely you had some bad third party repository. The plasma crash you had was pretty much the result of GStreamer trying to load an incompatible plugin which made it blow up. Why or how it was incompatible I unfortunately can't say from the backtrace.

If a new Fedora 23 works again I think we're best served simply forgetting about this :)
