tab completion doesn't work for eog and ppm files

[Timothy Miller]

I've noticed that tab completion doesn't work for eog if I'm trying to do completion on a ppm file. If there are, say, jpeg files in the directory, tab completion works. But with ppm files, tab does nothing.

Here's an old Red Hat bugzilla entry for the same problem:
https://bugzilla.redhat.com/show_bug.cgi?id=1090481

According to them, the bug was fixed up-stream months ago, so I'm guessing that Ubuntu has retained an out-dated version of EOG, and you may want to update it to fix this bug.
