Description Joshua Clark 2015-03-14 01:42:38 UTC

Application: plasmashell ()

Qt Version: 5.4.1
Operating System: Linux 3.19.0-1-ck x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
Every time I try to create a new activity in the activities manager,  it doesn't actually create the new activity. Then, shortly after trying to do this, plasmashell crashes with a segmentation fault. Even though it says I compiled from source, the source actually came from arch linux. I merely changed the PKGBUILD in the relevant packages to Debug so that I could print a useful backtrace. I can provide any more information that you might need upon request. I tried to see if I could narrow down the problem, but I'm too unfamiliar with the source code and qt5.

The crash can be reproduced every time.

-- Backtrace:
Application: plasmashell (plasmashell), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".

I figured it out. I had a file named "kactivitymanagerdrc.lock" in my .config directory. I removed the file and all is well now. I suppose a crash or sudden shutdown might have caused this. I guess the question is whether or not code should be added to detect the lock file so that regular users don't have this problem.
