I can't find a broken image in a levelset's graphics.

[Algebroot]

I've decided to play a specific levelset when this error appeared while loading:

img_load() failed: bytes per line is too large (corrupt?)

The error message told me to check stderr.txt for details. I checked stderr.txt, but all I see is this:

rocksndiamonds.exe: fatal error: IMG_Load() failed: bytes per line is too large (corrupt?)

That doesn't help...
