Description Alvin 2016-09-27 13:22:59 UTC

Application: krunner (5.7.5)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.7.4-200.fc24.x86_64 x86_64
Distribution: "Fedora release 24 (Twenty Four)"

-- Information about the crash:
- What I was doing when the application crashed:
Typing spectacle. I got as far as 'spec'

- Unusual behavior I noticed:
Spectacle itself crashes on close when launched from the command line
(segfault at 7fa2d20b5160 ip 00007fa2eb87faf0 sp 00007fff1e0cb578 error 4 in libQt5Core.so.5.6.1[7fa2eb765000+472000])

The crash can be reproduced sometimes.

-- Backtrace:
Application: krunner (krunner), signal: Aborted
