Hey,

I just committed code to change how Beagle launches external programs.
This will mainly affect the filters that use external programs (PDF,
RPM, video, spreadsheet, and external) as well as the tiles in
beagle-search.

It's probable that there are bugs, so please hammer on it and see if you
see any broken behavior related to indexing these file types or opening
the tiles in the UI and file bugs if you do.

Thanks,
Joe
