Description Artem Goncharov 2015-04-17 08:44:46 UTC

Application: plasmashell (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 4.0.0-0.rc5.git4.1.fc22.x86_64 x86_64
Distribution: "Fedora release 22 (Twenty Two)"

-- Information about the crash:
- What I was doing when the application crashed:

Tried to pin Firefox between Pager and Task Manager widgets

- find Firefox in Menu->Application->Internet
- Try to pull it with the mouse between Pager and Task Manager widgets

in my case crash occured always after widget shifts (i.e. pull it between "K" and Pager but do not release, pull it further between Pager and Task Manager)

lower panel setup:
K | Pager | Task Manager | System Tray | Digital Clock | Lock/Log out

The crash can be reproduced every time.

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

The crash backtrace

Comment 8 Jasem Mutlaq 2015-07-12 08:43:14 UTC

Getting the exact same problem on Kubuntu 15.04

Is any Plasma developer going to comment on this? This is a simple and common task, why is it crashing so often?

A (minor) Plasma dev here. It's not exactly crash in our software, as you can see in the backtrace, the thread with [KCrash Handler] in it (thread 1), has 50 lines (frames) and only 4 of those frames are from our code, the rest is Qt. It's crashing in some xcb/cursor interface, so can very well be a bug in some Qt versions.

That said, can you install libqt5gui debug symbols (qtbase5-dbg on *buntu) and post updated backtrace? It's enough if you select only the part with "[KCrash Handler]" in it.

Thanks

Backtrace with debug symbols compiled in

The backtrace looks a bit different from the one posted by Artem Goncharov but the problem is the same.
