Large Image causes Template Missing Error

Hey there, I got the same error, however it turned out that my image was corrupted.

I used a downloaded a version of the piano.png of Ryan Bates Railscasts episode 332 (Refinery CMS Basics). However I selected "save target as" on the image links shown here: https://github.com/railscasts/episode-332/tree/master/images which is nonsense of course as you have to click on the image to make it visible first. I ended up with two 27 k "png" files which were basically corrupted files, not images. However I did not recognize it in the first place.

So it worked great with the actual images.

The actual problem seems to be an unhandled exception in Dragonfly (at least in my case). According to the Gemfile I am currently using version 2.0.0, this was the default after doing gem install refinerycms

note:

maybe a file being too big causes the same behaviour than a corrupted file as its type/content may not be determined correctly.

Excerpt from below:

None of the functions registered with #Dragonfly::Analyser:0x0000000225c180 were able to deal 
with the method call format(<Dragonfly::TempObject tempfile=#<File:/tmp/RackMultipart20120316-4990-5betch (closed)> >). 
You may need to register one that can.
