Description animtim 2016-05-10 09:15:39 UTC 
Application: krita ()

Qt Version: 5.6.0
Frameworks Version: 5.21.0
Operating System: Linux 4.6.0-desktop-0.rc5.1.mga6 x86_64
Distribution: "Mageia 6"

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

I was using the transform tool, entered values in the tool options to move layer content precisely.

Then I tried to apply it by pressing enter. It didn't seem to work, so I clicked on the paint tool icon, and it crashed.

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

Comment 1 Halla Rempt 2016-05-10 10:37:21 UTC 
Hi Animtim,

Is this crash reproducible? The backtrace looks extremely strange and it must be some sort of broken memory access., If it's reproducible we can try to debug with valgrind.
Comment 2 animtim 2016-05-10 11:16:59 UTC 
I just tried to reproduce but couldn't yet.
Comment 3 Raghavendra kamath 2016-05-12 09:23:30 UTC 
I am experiencing this too,

actually this was a older bug which re surfaced again , I closed it earlier because it was not easily reproducible.

But now i get this crash for 3 out of 5 times while transforming , i got 4 crashes yesterday alone.

The older bug is here -> https://bugs.kde.org/show_bug.cgi?id=360786 ,
I am marking it a duplicate of this bug


the back trace from last crash generated by bug report wizard is as follows:

Comment 6 Halla Rempt 2016-05-23 11:21:44 UTC 
That's actually an assert right inside Qt itself!
Comment 7 Patrice Kouame 2016-09-10 21:20:40 UTC 
Should this still be open?  I can't reproduce the scenario.
Comment 8 Larpon 2016-09-15 08:55:00 UTC 
I'm getting crashes almost every time I use the 'Transform Mask' layer type with lastest 3.0.1 (stable) on Kubuntu 16.04 using the appimage. Might be related?
Comment 9 ugxt 2016-10-04 05:18:17 UTC 
I'm experiencing the same sort of thing on Linux Mint 18 Cinnamon. Whenever I apply a transform, the program instantly closes without any error messages or anything.
Comment 10 Halla Rempt 2016-10-31 15:19:58 UTC 
Hm, I just closed another bug reported by Wolthera with exactly the same backtrace as Raghukamath's latest -- the QRegion one. One thing all these reports have in common is that the crash seems to happing inside. Qt.

Please everyone -- if you can reproduce, please tell me which exact build you're testing, and which version of Qt you've got.

The hang on saving is reported here: https://bugs.kde.org/show_bug.cgi?id=370566
Comment 12 Halla Rempt 2016-11-03 14:20:17 UTC 
Er, that wasn't meant for this report.
Comment 13 Richard Raimund 2016-11-19 05:55:35 UTC 
Same for me, crashes each time transform mask applied, no crashes with transform tool though.
Comment 14 Beatrice 2016-12-04 16:50:54 UTC 
I'm also experiencing this bug. 

Running Krita 3.0.94 directly from the appimage. 

Looking over synaptic, currently installed version of QT is QT4 "4:4.8.7+dfsg-5ubuntu2", which tells me that it's probably 4.8?

Running Linux Mint's Cinnamon interface over an existing Ubuntu 16.04 LTS intallation.

I hope this information is useful in fixing this bug, and let me know if there's anything else I can do to help!
