Description korodimi 2016-03-31 05:35:57 UTC

Application: kate (15.08.3)

Qt Version: 5.5.1
Operating System: Linux 4.4.5-200.fc22.x86_64 x86_64
Distribution: "Fedora release 22 (Twenty Two)"

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

1.) Start Kate without opening any files and only "Untitled" is displayed
2.) Choose File menu -> Open recent -> select any recent files
3.) Kate (version 15.08.3) crashes immediately with "Signal: Segmentation fault (11)"

The crash can be reproduced every time.

-- Backtrace:
Application: Kate (kate), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Cannot reproduce with version 15.12.3

Comment 2 Dominik Haumann 2016-04-05 19:29:17 UTC

Can you please update to either the Applications 15.12 release, or maybe even to upcoming 16.04?

We haven't been able to reproduce, unfortunately... Further details would maybe help.
