What exception is it exactly? Can you tell the value of Exception.Message?

I personally encountered problems when dealing with RLE compressed 
bitmaps, which are quite common. For example, the icon sets from GlyFX 
use RLE encoding, which Lazarus/LCL can not handle. I recently provided 
a patch, but the discussion about accepting this patch or not 
unfortunately has died.

This would help very much; I think you can simply post your file to this 
mailing list, if it's not too huge.
