vcut segmentation fault

I am forwarding Debian-bug 818037 from user Frank Heckenbach f.heckenbach@fh-soft.de. Original bug report:

Sorry for the brief description, but for what I can tell, that's
really it. I tried various cases, and vcut always seems to just
segfault. Here's one example:

% head -c 500000 /dev/zero | oggenc -Q -r -o 1.ogg -
% vcut 1.ogg 2.ogg 3.ogg +1
Processing: Cutting at 1,000000 seconds
Segmentation fault

Tried on both i386 and amd64.

It did work correctly under squeeze and wheezy.

I am going to provide a patch down in the comments.
