This backtrace is not sufficient ...
For a proper backtrace
is needed to find the source of the problem. This
means that you will have to recompile digikam, libkexiv, exiv2, ... and
so with debugging enabled.
See http://www.digikam.org/?q=contrib under
"If you are experiencing crashes with digiKam" and
for installation instructions "http://www.digikam.org/?q=download/svn"
under "Install digiKam in your Home Directory".

Which digikam version (and Kipi, KExiv2, Exiv2, KDcraw, Dcraw, ...)
do you use (see About/Digikam)?

Can you convert raw files using ufraw?
