#24 Segfault at encoding time when pressing Ctrl+C twice.

[SeedmanJ]

It seems that on an ubuntu 32bit distrib, with fluxbox as window manager,
when we capture the screen, if we press Ctrl+c once, the encoding starts, but if we press Ctrl+c once again with a precise timing,
recordmydesktop segfaults.

I debugged it to find out that it's caused by a thread-unsafe libtheroa function that is called.

Adding a pthread_mutex_lock around this function call resolves the problem.

Hope this helps.
