I first want to track down this problem befor I switch from stable exiv2-0.9.1
to exiv2-SVN to avoid a additional source of error.

I have uninstalled and reinstalled exiv2-0.9.1 from Gentoo ebuild and the
problem is still there. I do NOT have other exiv2 installs flying around.
Here is another log + gdb bt:

Hope this helps. I am pretty clueless how I should track this problem down. I
guess I will manually compile exiv2-0.9.1 this evening to see if there is
something wrong with the ebuild.
