Description Jacob Kauffmann 2017-07-02 02:54:52 UTC

Application: kwin_x11 (5.10.3)

Qt Version: 5.9.0
Frameworks Version: 5.35.0
Operating System: Linux 4.11.7-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
Clicking the "+" button in the Desktop Grid to add more virtual desktops.

This bug report was submitted through the Crash Reporting Assistant. I have compiled KWin with debugging enabled because it has been less stable recently on my Arch system. I am willing to compile additional packages with debugging enabled if it will lead to more useful information for the developers. I am using the proprietary NVIDIA driver.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".

As with every crash report from Arch this backtrace is absolutely useless. I'm sorry but we cannot investigate.
