Description truekikim 2016-07-11 18:55:31 UTC
I pressed the shorctut to merge a layer with the layer below several times (like 4 or 5) and Krita crashed.

Reproducible: Couldn't Reproduce
Comment 1 wolthera 2016-07-11 19:04:53 UTC
Did you get a backtrace?

I am afraid that if you can't reproduce it could be like, a million things! We can't do anything with this report because we don't have any hints to what might be causing it :(
Comment 2 truekikim 2016-07-12 15:52:46 UTC
I did not get a backtrace. It happened again today and I am able to reproduce it. I work on a big file, so that may be the case (Its around 3000 x 12000). To reproduce it I just need to dupliate my paint layer several times then merge them down from the top one by one and a moment after it merges  when I press ctrl+z to undo last merge krita crashes.
Comment 3 Halla Rempt 2016-07-14 08:17:56 UTC
Are you using an appimage, a home-built Krita, or a version of Krita distributed by your distribution? Which Linux distribution are you using?
Comment 4 Halla Rempt 2016-07-14 09:02:03 UTC
I get this output when trying to merge a bunch of layers:

And if I just duplicate layers on a 15k x 15k image fast enough, I can get a segfault -- but no backtrace, since it doesn't happen when running in gdb.

Notes:
10:59:06 < dmitryK|log1> boud: the warning means that the the layer has been deleted while the update has been running, or  while it has been in a queue
10:59:53 < boud> that would also explain why I see the layer docker select the layer below the layer it should show; and then half-way through it selects the right layer
Comment 5 Raghavendra kamath 2016-07-15 12:17:56 UTC
I can reproduce this bug in linux.

here is my back tace

Comment 6 Raghavendra kamath 2016-07-15 12:21:24 UTC
If it helps i got another one , this time it crashes when i pressed undo after merging all layers.
also some layer are not editable , they show the tool tip of "group not editable"

Comment 7 Patrice Kouame 2016-09-10 18:12:24 UTC
Haven't been able to reproduce this bug. 
On latest master 2db4438671e17002c7b02e3ad3a5208930765e4f as of 10-09-2016
macOS Sierra GM
Xcode 8 GM
command line build with Xcode debugger

I tried to reproduce by creating multiple layers (some vector), repeatedly shortcuting (Cmd-E) to merge below. Even undo and redoing the entire stack rapidly multiple times.

I do have this log to share (RelWithDebInfo):

I know how to make the crash go away... But I still see this output.

Git commit f1d01ccf3fdcdb7fc6c49909e8767c333353422e by Boudewijn Rempt.
Committed on 15/09/2016 at 12:43.
Pushed by rempt into branch 'master'.

This way the user can at least still save their image. I can easily
reproduce the warning messages Raghukamath pasted into the bug report,
though.
