Description J.Fly 2016-12-16 14:10:54 UTC

Application: kwin_x11 (5.8.4)

Qt Version: 5.7.0
Frameworks Version: 5.28.0
Operating System: Linux 4.8.13-1-zen x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
I was entering the vendor ID for a usb device I wanted to access in my guest OS and when I pressed tab to go to the product ID kwin crashed.  It crashed again when I entered the product ID and then crashed again when I pressed save. No virtualbox systems were actually up and running.  I did have firefox open at the time as well.  I was typing in the IDs from guake.

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

Comment 1 Martin Flöser 2016-12-17 08:52:17 UTC

Unfortunately the backtrace is lacking debug symbols (normal for Arch based
distros). This means we don't see where it crashes and cannot investigate.
