We are currently testing a resolution to this issue and will have an update soon.

If you are using X2Pro version 3.0.5 and you are getting the same error message when you try to convert your project, please create a new forum topic, and include the following information:

1. The text from the error message (copy/paste the text, please don't attach a screen grab)
2. The FCPXML (attach it to your forum post)
3. The version of FCP X that you are using
4. The version of OS X that you are using
5. Whether you have the "Trim embedded audio" option selected
6. What duration you have the "Trim handles" set to in the preferences

..and we will contact you directly, with a potential workaround.
