Description Alexander Bantyev 2017-06-22 20:04:08 UTC

Application: plasmashell (5.10.2)

Qt Version: 5.9.0
Frameworks Version: 5.35.0
Operating System: Linux 4.9.33-1-MANJARO x86_64
Distribution: "Manjaro Linux"

-- Information about the crash:
- What I was doing when the application crashed:
I was trying to delete a symlink from trash in quick preview. An actual error was something like "trash protocol doesn't support symlinks.", and Plasma crashed.

The crash can be reproduced every time.

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