I gave michi's branch and test videos a try. For the six videos being thumbnailed in parallel, I see two successful thumbnails, two instances that look like they died due to invalid memory allocations:
(vs-thumb:15299): GLib-ERROR **: /build/buildd/glib2.0-2.45.1/./glib/gmem.c:357: overflow allocating 4294967274*8 bytes
(vs-thumb:15298): GLib-ERROR **: /build/buildd/glib2.0-2.45.1/./glib/gmem.c:357: overflow allocating 4294967274*8 bytes
And two that have stuck around eating a little more than one CPU each. I was able to kill -9 them though.
