Comment 8 for bug 312632

I changed the status to "incomplete".

Just tried with EyeOfGnome (eog) 2.26.1, and the problem still exists. I personally tested with Ubuntu Jaunty 9.04, and I had someone else test in Ubuntu Karmic 9.10.

Steps to reproduce.

 1) Open any image with EyeOfGnome (Image Viewer) in Ubuntu.
 2) File --> "Save As"
 3) Now, we're prompted with a "Name". Call it "my picture I am saving"
 4) Click "Save"

ERROR: File format is unknown or unsupported - Eye of GNOME could not determine a supported writable file format based on the filename. Please try a different file extension like .png or .jpg.

OK, look at this, there's a "File type" drop down menu, currently said "All Images".
Try changing this to "JPEG" or "PNG", try again, same error.

There are two options here:
 A) [RECOMMENDED] When the user choses the filetype, it should automatically suffix the "Name" entry with that chosen filetype.
 B) eog shouldn't care if an extension exists (I don't think this is good though -- it is preferred to suffix images with the proper extension for its type)

Here's my version on 9.04:
$ dpkg --list | grep eog
