Description wolthera 2017-10-26 14:55:18 UTC 
To reproduce:

1. Go to the internal color selector dialog(by pressing the dual color buttons in the tool bar)
2. Try to fill in numbers in the RGB spinboxes.

Touchdocker is not visible, and also doesn't work here due to the same QML path issues that also plagued 2.8 that I cannot be bothered to figure out how to fix.

Comment 1 Halla Rempt 2017-11-08 13:25:47 UTC 
I get this crash on opensuse. I am not sure what it's about, since this seems to happen almost completely inside Qt, except that it passes 3 times through KisApplication::notify

Comment 2 Halla Rempt 2017-11-09 14:48:32 UTC 
I suspect that this is a variant of 385864, only with a slightly different backtrace because the error hits a similar condition in another Qt library
