Comment 40 for bug 852923

In reply to comment #28 : does this fix currently work with the Mate desktop environment ? I've been trying with Mint 12,Mint 13 and Mint Debian and I can't see any raw (Cr2) thumbnail at all,furthermore according to this issue https://github.com/mate-desktop/mate-file-manager/issues/21 , Mate *can't* actually -as of now- handle this kind of files,as this excerpt clearly states "Caja [Mate file manager] doesn't have any support for displaying CR2 file thumbnails."
Am I missing something here ? I've been trying to see my CR2 files for a while now,if there's any kind of fix/workaround that actually works I'd be happy to try it.
