Description Jonathan Ringstad 2015-05-12 15:17:11 UTC

Application: krita (2.9.4)
KDE Platform Version: 4.14.7
Qt Version: 4.8.6
Operating System: Linux 4.0.1-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
1. Open two documents, untitled, unsaved, modified.
2. Create a secondary window, put it on secondary screen
3. In secondary window, open a view of one of the two existing documents with no name
4. Close the view that was just created
5. Krita may crash

If the crash does not occur immediately, try creating yet another view in the newly opened window -- that seems to reproduce the crash 100% of the time.

The crash can be reproduced sometimes.

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

Comment 1 Halla Rempt 2015-05-15 09:40:03 UTC

Hm, no, I didn't get any crash. I was able to close all modified, unamed views on all documents without being asked whether I wanted to save, though, which is also really bad.

Comment 2 Jonathan Ringstad 2015-05-15 09:43:48 UTC

If it doesn't repro immediately, try opening and closing views in the secondary window a few times. That tends to reproduce it 100% reliably for me.

I can recompile with debug symbols and attach a better trace.

Comment 3 Jonathan Ringstad 2015-05-15 10:18:37 UTC

backtrace from crash

Comment 4 Jonathan Ringstad 2015-05-15 10:22:02 UTC

I noticed that when the assistant is turned off, the crash does not occur. The backtrace also seems to hint at the assistance being at fault.

Comment 5 Halla Rempt 2015-05-20 12:33:25 UTC

Hm, no, sorry -- I still haven't got the sequence right that reproduces the issue. Could you try to reproduce with debug symbols installed?

Comment 6 tokiedian 2015-11-05 16:56:32 UTC

I have an similar problem with krita in my windows 8.1. Make two documents in tab, switch krita to subwindow mode, click one subwindow then click the other and krita will crush.

Comment 7 Halla Rempt 2016-03-19 15:16:18 UTC

Okay, I can confirm with current git master.

Comment 8 tokiedian 2016-04-17 16:57:23 UTC

I've confirmed the bug has resolved in 3.0 alpha1 (2.99.89) on ,my windows 8.1.

Comment 9 Halla Rempt 2016-04-17 17:43:35 UTC

yay!
