For some reason I can''t catch an exception thrown by rmagick inside the app. After an invalid image file is uploaded the process just hangs.

Originally I had installed ImageMagick via Debian''s apt-get and built the rmagick gem using "gem install rmagick". This wasn''t working so I uninstalled ImageMagick and tried to
