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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/427100 Title: JPEG2000 thumbnail causes browser to crash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/jasper/+bug/427100/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
