OK, see below for this.

None I'm aware of.

OK, please do the following:
1) grab the attached import_ffmpeg.c and drop it into import/ directory
of a 1.1.5 source tree, effectively replacing the shipped one.
The new plugin has this version tag: "v0.1.15D (2008-01-28)" (note the
trailing `D')
2) recompile and install at least the affected plugin; rebuilding the
whole package won't hurt but's almost useless.
3) retry. transcode will crash anyway but we get a bit more of
information about what's going on.
4) please provide the full transcode output and backtrace as you already
did.
I got a theory about what's going on, but it will take some try-and-see
cycles to narrow it down.
Bests,
