[Bug 58598] (PATCH INCLUDED) Seeking bar jumps to zero when dragging or scrolling

[Liu Qishuai]

Public bug reported:

Binary package hint: totem

When playing rmvb files in totem-xine, if I scroll the mouse, the
seeking bar jumps to zero and then jumps to the correct place. If I
scroll the mouse quickly, it may jump to the start.

Steps to reproduct:
1. Install totem-xine (apt-get install totem-xine) and some codecs.
2. Open an rmvb movie.
3. Drag the seeking bar to a place.
4. Watch the seeking bar carefully when doing step 3. It firstly jump to zero and then jump to the correct place.
5. Scroll the mouse quickly. It will probably jump to start of the movie. This should not happen.
