Looks like the crash is on this line

    va->vobs[i]->vobu[0].vobcellid = 1; /* ensure first vobu starts a cell */

with va->vobs[i]->vobu = NULL. That must mean no VOBUs were found in
the input movie file. In the old days (pre-IVTV-patch), you would see
the warning “Skipping sector, waiting for first VOBU” if there were no
placholders to put the NAV PACKs. But 0.6.18 should be synthesizing
the necessary NAV PACKs as necessary to start new VOBUs. Is the user
seeing that warning appear?

I can create an identical-looking crash by specifying a zero-length
input movie file.

This is another case where I’d really like to see the input movie
file. Even the first few megabytes ought to be enough.

I have put in a check for this condition, to report an error instead of 
crashing.

I would still be interested to see how this could happen with a 
non-zero-length file, though.
