2267	Do we get the right file extension with mime.get_primary_extension(mime_type) ?	erikos	tomeu	"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'.

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.
