I've reproduced this in the latest (development) version. crnlib's DDS reader 
is in dds_texture::read_dds_internal(). It looks like this function is failing 
to handle non-DXTc files which use dwLinearSize vs. lPitch:

        dwSize  124 unsigned int
        dwFlags 528391  unsigned int
        dwHeight    52  unsigned int
        dwWidth 52  unsigned int
        lPitch  10816   int
        dwLinearSize    10816   unsigned int

dwFlags is 0x00081007, and DDSD_LINEARSIZE is 0x00080000, but lPitch and 
dwLinearSize are unioned.

The fix should be pretty easy. I'll fix the latest development version first. 
Thanks a bunch for the report.

Just grabbed the source using svn and it seems this bug has not been fixed, 
should I expect it to be fixed?

Hi Christian - Yes, I've fixed this in my local development branch. Apologies 
for the delay, I've been pretty slammed with other projects, so I haven't had 
much time to work on crunch a whole lot. I'll try to release my current devel 
version to a branch in SVN within the week.

Or you could zip it up and dropbox it for me...

I've checked the latest code into SVN. This problem is hopefully fixed.
