FCPX 10.0.5 on Mountain Lion Crashes on Export

Hey Folks:

Recently upgraded to 10.0.5 and ML. Seems more stable and faster...BUT, it crashes every time I try export (command-e). I can export to Compressor settings and Compressor itself, but can't just do a straight up export, which is my preference.

Have trashed prefs and run digital rebellion's housekeeper. Any thoughts? Any body else with this issue?

Thanks!

It's most likely something in the project, some corrupt file, or render file, or font, or graphic.

Try deleting ALL the render files for both the project and the events. Restart, open the project, re-render what is required and then try your export. Often times the corruption in a project is associated with a bad render file.
