Bugfix release with the following fixes:
* Fix thumbnail creation for input files with dot
* Use native python to generate list of external commands
* Do not use commandline arguments in test mode
* Catch broken symlinks in the library and filter them
So everything but the last item is essentially what we had in
fixes.patch, hence we cane remove it.
