Openshot Failing

Richard: Do you still maintain Openshot for RPMFusion? I'm getting the following error when trying to start Openshot: ------------------------- ERROR 1 ------------------------------ Failed to import 'from openshot import main' Error Message: cannot import name main ---------------------------------------------------------------- -------------------------------- OpenShot (version 1.4.3) -------------------------------- Process no longer exists: 2738. Creating new pid lock file. No LADSPA plugins were found! Check your LADSPA_PATH environment variable. mlt_repository_init: failed to dlopen /usr/lib64/mlt/libmltavformat.so (/lib64/libavcodec.so.54: symbol avpriv_update_lls, version LIBAVUTIL_52 not defined in file libavutil.so.52 with link time reference) Detecting formats, codecs, and filters... Segmentation fault (core dumped) OpenShot is installed from RPMFusion, along with mlt, ffmpeg and ffmpeg-libs (all x64_86). Here are the versions installed: openshot-1.4.3-1.fc19.noarch ffmpeg-1.2.4-2.fc19.x86_64 ffmpeg-libs-1.2.4-2.fc19.x86_64 mlt-0.8.8-5.fc19.x86_64 This seems to be an issue ffmpeg, but I'm not sure (see this thread as an example https://bbs.archlinux.org/viewtopic.php?id=135215). Do you have any suggestions as to how to proceed to track down this error? Thanks, George
