Description Simon 2015-04-07 21:48:51 UTC
Application: plasmashell (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-12-generic x86_64
Distribution: Ubuntu Vivid Vervet (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
Not always, but quite often I get a plasmashell segfault as soon as I try to open the activity switcher (I open it through an icon/widget in my main bottom panel). After a crash I can open the activity switcher just fine and switch to my other activity (I currently have 2). Plasmashell will crash quite often once i do some work in one activity, and then try to switch to the other activity.

I followed the "How_to_create_useful_crash_reports" article, but unfortunately some libQt5 dbg symbols are missing and they don't seem to be available in Kubuntus repositories. plasmashell dbg symbols are missing as well. Please let me know how to install them, because I'm experiencing other plasmashell crashes in different areas and I'd like to report those and provide as useful backtraces as possible.

I'm using the Kubuntu 15.04 beta  (64 bit) with an ATI HD5850 and the xorg ati drivers. Please let me know if I need to provide more information, I'm not quite sure what else might be relevant.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault

Comment 2 David Edmundson 2015-04-07 22:30:24 UTC
do you use the standard Breeze theme?

My "Desktop Theme" is "Prometheus" (exported from Manjaro Linux which is also running Plasma 5)
but everything else is Breeze (icon theme, widget style and window decoration)
