Do you have a current version of kdelibs/kimgio/ico.kimgio?
I recently changed the Header regex for .ico/.cur files from \001\001 to 
\001\001[\001|\002]\001 so if you still have the old version, it might match 
on TGA. Grr, doesn't it suck that both TGA and ICO/CUR have no real "magic" 
header? A .cur (Windows cursor, essentially the same as .ico) file starts 
with 0x00 0x00 0x02 0x00, so any TGA with that start will still be considered 
a CUR file if the ico/cur reader is registered first and all .cur files will 
be treated like a TGA if that reader is registered first.
