I've been seeing a few cases here and there about capitalization mismatching between the files we have under img/interface/icons/ and the files that are being called from the char.php view.
One of my members reported it fixing itself after he uploaded the method CharacterProfiler (as opposed to the Armory sync that I kick off from time to time)
An example member with the graphic problem is here:

The image linked is here:
Broken
Spelled incorrectly as:
INV_Mace_1h_Stratholme_D_01.jpg
The correct spelling is:
INV_Mace_1H_Stratholme_D_01.jpg
(Note the H in 1H)
