directories with names ending with known image extensions cause crash in 2.2 and unexpected behavior in 3.1

[GoogleCodeExporter]

What steps will reproduce the problem?
1. create an empty directory foo/
2. put a valid 1.bmp file in foo/
3. mkdir foo/2.bmp (so now foo/ has two children)
4. open 1.bmp in xee

What is the expected output? What do you see instead?
Xee should skip 2.bmp/ because it is a directory.
In v2.2, Xee often just crashes.
In v3.1, Xee can show funny things on screen.

What version of the product are you using? On what operating system?
tried both 2.2 and 3.1 on OS X 10.7.5

Please provide any additional information below.

Hahah, when I looked the code over, it seems I started writing the code to 
avoid that, and then forgot about it. Should be fixed now.
