 I copied a photo taken with Record on a usb key. The file extension shown
 when inserting on another machine was .jpe Since I did not knew that
 extension I checked the Sugar code path. What we actually do is, we merge
 all the existing mime/globs in a dictionary with the given mime type as
 key and then get the value of that key.
 {{{
 jfif
 jpeg
 jpg
 jpe
 }}}

 In the blobs there are 4 keys (image/jpeg) and hence we do overwrite the
 value and end up with the last key-value pair found - in this case 'jpe'.

 base/repos/mainline/blobs/master/src/sugar/mime.py#line144

 Not sure there is a good priority one should follow. Maybe we should check
 what nautilus or others do, or define the extensions for the most common
 cases.
