MPlayer interrupted by signal 11 in module: seek
- MPlayer crashed by bad usage of CPU/FPU/RAM.
  Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and
  disassembly. Details in DOCS/HTML/en/bugreports_what.html#bugreports_crash.
- MPlayer crashed. This shouldn't happen.
  It can be a bug in the MPlayer code _or_ in your drivers _or_ in your
  gcc version. If you think it's MPlayer's fault, please read
  DOCS/HTML/en/bugreports.html and follow the instructions there. We can't and
  won't help unless you provide this information when reporting a possible bug.

The problem is that in libmpdemux/demux_avi.c:demux_seek_avi()
sh_video is NULL, and the crash happens in line 609:

    int rel_seek_frames=rel_seek_secs*sh_video->fps;

        of the darkness. There had been need of rain for many days.
       "Only a promise," Lao Er said.
