Description RJVB 2017-05-23 17:16:42 UTC

Application: kdevelop (5.1.1)
 (Compiled from sources)
Qt Version: 5.8.0
Frameworks Version: 5.32.0
Operating System: Darwin 13.4.0 x86_64
Distribution (Platform): MacPorts Packages

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

Preparing a commit, wanted to add a few comments to my changes. Entered one and then hit the "next change" button without saving first. Boom.

The crash can be reproduced sometimes.

Comment 1 Kevin Funk 2017-06-29 18:56:45 UTC

I presume this is fixed.

Comment 2 RJVB 2017-06-29 20:07:53 UTC

Why would you presume that? Because I haven't reported other occurrences in a month?

Comment 3 Kevin Funk 2017-06-29 20:49:25 UTC

Because this patch (see "Latest commit" field) claims to address/fix the issue:

Comment 4 Piotr Mierzwinski 2017-09-01 21:56:30 UTC

@Kevin
I met this crash in version 5.1.2, so I think this is not fixed fully.
Please check bug report with Id: 384272

Tested with: kdevelop-git-5.1.2.r24258.76f2fdf774-1-x86_64

Comment 5 Christoph Roick 2017-09-01 22:37:36 UTC

It will only be fixed in 5.2.0.
