Description Johan Reitan 2015-10-22 07:18:44 UTC 
Application: kdeinit5 ()

Qt Version: 5.5.1
Operating System: Linux 4.2.3-1-ARCH x86_64
Distribution: "Arch Linux"

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

I closed the ktelepathy chat window. The same crash has occurred before when closing okular and dolphin (both kf5 branch) and probably others that I don't remember, but the crash does not occur every time.

The crash can be reproduced sometimes.

-- Backtrace:
Application: kdeinit5 (kdeinit5), signal: Segmentation fault

Comment 1 Johan Reitan 2015-10-22 07:22:04 UTC 
Sometimes when I close the error dialog, the session exits to sddm. This doesn't happen every time, and didn't happen when I filed this report.
Comment 2 Alexander Diewald 2015-10-26 20:40:05 UTC 
Same for me, using Gentoo with Qt 5.5.1 and plasma 5.4.2. Typically, multiple processes/applications are affected by this bug: plasma, konsole, ... But, however, this differs from crash to crash; I cannot see a pattern there.
Ironically, this happened when closing a useless trace displayed in drkonqi.

Plasma crashes in dual monitor configuration.
Kubuntu 15.10, dual activities, two desktops each.

Sometimes there's e single side crash (only left or right display involved) of a single destop (in all acrivities), sometimes crashes one Desktop of two (in all activities), more often crashes all.

Crashes happen frequently closing application in any predefined way: so can happen quitting from menu, with quit keyboard command, or clicking [X] top left button.

Clicking top left button is nearly sure to make crash happens.
