Andrew / RafaMar: We can not reproduce the error using Andrew's file. The interesting information is that 2 people have now reported this error. Andrew report shows:

FileSystem::update /home/guest/MLP FIM 1 Karusel Нет такого файла или каталога Assertion fctx->async_lock failed at *libavcodec/pthread_frame.c:155*

RafaMar report shows:

MWindow::init_ladspa_plugins: can't create ladspa plugin index: /home/MIUSUARIO/.bcast5/ladspa_plugins._usr_local_lib_ladspa Assertion fctx->async_lock failed at *libavcodec/pthread_frame.c:155*

The error is coming from running ffmpeg in conjunction with Cinelerra but I think 2 different operating systems with the report from RafaMar stating Debian stable.
