It's a problem with MIDI playback and some hardware, not all. Timidity fixes it because that makes prboom use software MIDI playback rather than hardware. It shouldn't be a dependency because not all hardware MIDI is affected.
I think it's a bug in the SDL mixer library. You can get around it by either touching /etc/timidity/timidity.cfg or running with -nomusic (which still gives you sound effects). ** Bug watch added: Debian Bug tracker #472087 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=472087 ** Also affects: prboom (Debian) via http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=472087 Importance: Unknown Status: Unknown -- [apport] prboom crashed with SIGSEGV in free() https://bugs.launchpad.net/bugs/101936 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
