Just came across another issue:
a friend of mine installed navit 0.5.0 from scratch out of http://www.chollya.org-Repository
and the menu-icons were missing completely.
He found out, that installing librsvg2-2 and librsvg2-common solved that issue.
Would it be possible to add these two to the navit-dependencies to prevent future problems?

CU and merry christmas!
