A prerequisite for this bug is that Tool Option location is in the docker and that there is an open file. =Reproducibility= I have tested it three consecutive times without fail. =How to reproduce= 1) Have the Tool Options docker visible; 2) "Configure Krita" > General > Tools > Tool Options Location > In Toolbar; 3) Press OK; 4) Choose any tool that will change the content of the Tool Options docker. I first encountered the bug by pressing "V" to engage the straight line tool) or perform any action that will do the same. =Result= Krita will crash. Any unsaved result will be lost unless an autosave is available. =Expected result= The dialog window that allows to change the Tool Options location states that Krita needs a restart after the operation. This appears to suggest that doing so is not strictly necessary to keep using the program.
Clarification/rephrasing for the expected result described above: "The assumption is that restarting Krita is needed to apply the setting and that there is no suggestion that doing so is strictly necessary to keep using the program."
Created attachment 103172 [details] (GDB Report of the crash) Yes, I can reproduce the crash on Ubuntu 14.04 - Krita 3.1.1.
