SIGSEGV on rendering to H.264

[bella]

Problem: When rendering to H.264, rendering fails in background with a segfault and GUI hangs displaying 0% progress. No further rendering or normal exit possible, due to "rendering in progress".

Expected: Report problem to user and return to normal operation.

Context: I am using Ubuntu 10.04 amd64, cinelerra-xt installed from repos, what else should I provide?

Note: I've read about x264 problems in  https://help.ubuntu.com/community/amd64/Cinelerra, even if those instructions work, the GUI should not hang.

Can't reproduce that segfault on gentoo 64bit using a self-compiled version of CinCV from the git repository at the moment. Furthermore the GUI did not hang here, nor complained erroneously about "render in progress".

However, my resulting video does not play in mplayer nor in VLC, only sound is working. I have been using "Microsoft AVI", with twos complement audio, 16 bit linear, both, "H.264" and "Dual H.264" with bitrate 2000000 and a fixed quantization of 5.
On the terminal I get warnings from x264: "x264 [warning]: non-strictly-monotonic PTS". I'll investigate that further as time permits.

Can you post the used render-setting please?
