     What's going on here is that the profile code is looking at the
input and output frame sizes and aspect ratios and choosing "proper"
clipping and zoom values; unfortunately, the profile code in 1.0 is
rather broken and doesn't take into account any additional clipping
options you give.  We're working on a better system for 1.1, but in the
meantime you'll need to avoid using --export_prof if you also give a -Y
option.  (Alternatively, you can use -Z and give the input frame size as
the zoom size, but since this still causes a zoom operation to occur,
the encoding process will be slowed down.)  You should also give the
same value for --import_asr as you use for the export aspect ratio
(default 2, for a 4:3 ratio, but you should use --export_asr explicitly)
to avoid the automatic clipping (and apparently to avoid a segfault, to
judge from your second log).
