Created attachment 110998 [details] Crash log Krita reproducibly crashes when doing the following steps, after selecting a template for drawing: (1) "Settings / Dockers / Palette" - opens an empty palette docker. (2) Select "default" palette. (I have to click on the "Choose palette" button, then, select "Default", then click outside the dialog (please note that this is confusing as there's also a Save button which I used first but which does not close this dialog)) (3) Click "+" to add a color (color appears at the end of the palette) (4) Click "the red crossed circle" to delete the same color (5) Krita crashes Attached the kritacrash.log.
Hi Peter, I can reproduce the crash, but only on Windows.
Yes, I can confirm that on Ubuntu 14.04 with the latest Krita beta 4, it doesn't happen.
*** Bug 395019 has been marked as a duplicate of this bug. ***
I cannot reproduce this crash anymore, not even on Windows.
I can still reproduce it on Linux. I can't get a backtrace though because running gdb and causing this crash freezes my whole desktop. Linux is still fine as Ctrl+Alt+F1 works. Installing the krita-testing from krita-lime (version: 4.0.0-0~201806031110~ubuntu17.10.1) doesn't crash but my self built version with symbols (version: 4.0.0-0~201804081023~ubuntu17.10.1) does crash.
The trick to working with gdb when a crash happens in a popup window is to start gdb in a virtual terminal, attach to the running krita and then reproduce the bug. Back in the text terminal, gdb can then print a backtrace.
Thanks boud, that's a neat trick. Got the backtrace.

Ha, that helps -- it shows where the crash happened. But since this was built from the krita lime sources, then that didn't include the patch that fixed the issue. In both master and krita/4.0 line 181 in palettedocker_dock.cpp is actually blank, and the check for a valid colorset is present.
