3 months ago Interesting, looks like a concurrency issue, though with limited impact luckily. Seems like there's also a chance it might affect other dialogs too, so I'll see if I can improve this. Thanks for the report!
This error is reported (not-crashingly) occasionally when configuring colors:
This error happens sometimes when I hit the cancel or ok button of the color configuration window. The window does not close as expected if the error is triggered.
