I can't reproduce, might be an opensuse problem, or 64bits problem.

Maybe this is an openSUSE issue.  The openSUSE packages are being used against Qt 4.5.  The distribution is supposed to publish KDE 4.2.2 packages shortly, hopefully they will also include some sort of refresh of Qt & Krita as well.  

Will retest scenario against new packages when they are published.  Are there any other variations of this scenario or methods you'd like included for the next go-round?

I have asked to some of our developer who use OpenSuSE to reproduce, and one of them was able to reproduce, with a different backtrace (but that might be because he have build krita in debug mode, while packages are probably not). From the look of both backtraces, it sounds more like a problem with color profiles. For some reason, either the profile got corrupted or a wrong profile is used.

Here is his backtrace:

This is also caused by a buggy lcms -- upgrade to 1.18 or downgrade to a version without "fixes" for the "security issue" that was applied to lcms 1.17.
