Sentry Crash Report:

Description Nicolas F. 2016-06-02 15:10:46 UTC

If a second window is opened, and assigned the view of the document in the first window, and then said second window is closed, Krita will crash.

Reproducible: Always

Steps to Reproduce:
1. Create a new document
2. Go to Window->New Window
3. In said new window, go to Window->New View->Unnamed
4. Close the new window.

Actual Results:  
Krita will close both windows as it crashes

Expected Results:  
Only the second window closes

This crash only happens if the window is opened after creating the document, apparently. If I create a new window first, then create a new document, then switch to the second window and assign the view there and close it, it won't crash.

Here's the backtrace

Comment 1 Odysseas 2016-06-02 15:15:36 UTC

In krita 3.0 I had this every time as well.

Comment 2 Alvin Wong 2016-06-02 15:27:12 UTC

Just tried to reproduce on Windows, The first time it didn't crash immediately but only when I choose "New Window" again after doing the steps once. The second time it crashed immediately though.

Comment 3 T Zachmann 2016-06-12 05:50:09 UTC

I can reproduce the crash. The problem is that the KisPaintopBox::setCurrentPaintop is changed when the new window is created. Once the new window goes out of scope the data in it are no longer valid. I'm looking on how to reactivate the current settings when changing the view.

Comment 4 Halla Rempt 2016-07-06 11:58:37 UTC

Thorsten, didn't you fix this issue?

Comment 5 speedyblueskyfish 2016-08-01 12:53:11 UTC

Im not sure if t his is the same bug, in krita version 3.0 I have a 100% reproducible crash:
crash when closing any "new window", but only if i have selected a template before opening and then closing the "new window".
in other words, if i open krita with nothing in it, and then select "new window" and close it, it will not crash. but if i have selected a template and then do it, it will always crash.

correction: not every time. this time it crashed when i selected "use template" when making a new window. maybe. or maybe it was just a delay before it crashed.

Comment 8 Nimthora 2016-09-08 12:47:07 UTC

Steps:
1. Open Krita
2. Window -> New Window
3. Close newly created window
4. Open image from file
5. Crash
