Comment 8 for bug 290728

In 8.10, this does get rid of the error message and the immediate exit, but xvidcap still can't record (after clicking the record button, all buttons grey out forever and nothing is written to test-0000.mpeg). Looks like maybe it has another dependency that I don't have installed.

If I attach to the process in gdb after trying to click the grey Stop button a few times, this is where it is (probably not very useful):
