Comment 1 Martin Koller 2013-03-10 08:57:29 UTC

What version of KDE are you using ?
The mentioned file kdeui/kactionclasses.cpp:1515 does not exist in KDE-4.10.1 sources.

But nevertheless, the crash happens outside of KDE code in the function FcFontMatch() of the fontconfig library, e.g.
http://cgit.freedesktop.org/fontconfig/tree/src/fcmatch.c?id=2.9.0#n548

What you can do to solve this problem is to remove the kolourpaint config file (or at least the line with the "Font Family" in it), e.g. ~/.kde4/share/config/kolourpaintrc
It would be interesting to know what that line defines in your file.
My file contains:
Font Family=Arial
