Status in OpenLP - Worship Presentation Software: Fix Released

Bug description:
Hello!

- xubuntu 10.10
- trunk 1106
- Debug log is attached

1) Start OpenLP and select the "Media" tab.
2) Open a video or audio file (I took the video files from the /resources/videos directory).
3) Preview one item (does not matter whether you double click it or press the preview button).
4) The following error message is shown, although the video will be previewed.

Traceback (most recent call last):
