Control: forwarded -1 https://bugs.kde.org/show_bug.cgi?id=463052 Dear Maintainer, I tried to have a look if I can find some more information, and opened an issue upstream here: https://bugs.kde.org/show_bug.cgi?id=463052 It looks like a double free because a pointer is hold in two lists. And it can be reproduced quite easily in i386 and amd64 by really just open and close Krita. Kind regards, Bernhard
