Is that reproduceable?
That backtrace is extremely puzzling: something weird is happening in the accessibility code of Qt -- it's not in Krita code at all.
I searched for it a bit, and it happens in other KDE apps as well: https://bugs.kde.org/show_bug.cgi?id=310797 https://bugs.kde.org/show_bug.cgi?id=305054 I actually think this might be a bug in some versions of Qt.
You can work around the problem by uninstalling the qt-at-spi package.
Reported it to Launchpad https://bugs.launchpad.net/ubuntu/+source/qt-at-spi/+bug/1127461
