Crash calling to_Image() on graphics lump objects about omgifol HOT 4 CLOSED

Is this also with the python3 branch, or master?

(the former is a work-in-progress attempt at making the package compatible with both python 2 and 3, which I've been kind of neglecting; I had wanted to eventually merge the branch back into master once it was stable. Thanks for giving it a bit more testing - I'll look at both issues soon)

Ah yes, I should have specified that this is with the master branch and Python2.

OK, found the issue - python on your system treats longs as 8 bytes rather than 4, which is the size that omg.Graphic.to_raw expects it to be when decoding the lump.

Rather than fixing this specific case just yet, I'd like to go through and make sure every call to struct.unpack is sufficiently strict about size/endianness, but in the meantime you can change the format string on L151 of lump.py to '<%il' which should be enough to fix exporting images.

Should be better in 301ca31, give it a try.
