Comment 21 for bug 427100

Wow, I remember finding this bug yeaaars ago and it still isn't fixed! Anyway, the bug is in libjasper. I downloaded the latest version, and here is what the "jasper" tool says:

$ ./jasper --input untitled.jp2 --output untitled.bmp --output-format bmp
cannot get header
jasper: jp2_dec.c:294: jp2_decode: Assertion `iccprof' failed.
Aborted (core dumped)

Terribly bad form for a library to call abort(). I haven't done any testing, but my image does have an alpha channel, which agrees with previous comments.
