eom-window: update image counter even if current thumbnail is for failed image

[whatdoineed2do]

To reproduce:

• obtain/create an image file, foo.png
• obtain/create unsupported (gdk pixbuf) file, foo.txt
• run eom foo.png foo.txt
  • displays foo.png, showing 1/2 in bottom right statusbar:
• navigate to 2nd file which is an invalid (image) file
  • eom displays "Could not load image 'foo.txt'"
  • status bar continues to incorrectly show "1/2", referencing the previous file

Post fix:

• as above, navigate to 2nd file which is invalid:

Thx, it works now.

You only need to create a text file with image file extension, eg. png. This will trigger the issue....

used your test with a "text.jpg" file and it worked: statusbar counter only updates properly with this applied
