If you pause a video and move the seek slider, the video will automatically resume playing while the Pause button doesn't change its appearance back to a Play button. Clicking the button will make it look like a Play button again, but both before and after the video is still playing. Clicking once more will make the button look like a Pause button and properly pause the video.

Reproducible: Always

Steps to Reproduce:
1. Open a video and let it play.
2. Pause the video.
3. Move the "seek slider" while the video is paused.
Actual Results:  
The video automatically resumes playing, while the Pause button doesn't visually turn into a play button until clicked again.

Expected Results:  
1. The behavior most people would probably want is not resuming a paused video when moving the seek slider. Moving the slider should of course update the video frame and properly take you there.
2. If it's intended to automatically resume the video when moving the seek slider, there's still a bug with the play button not sensing that the video  was un-paused and breaking until clicked.

Noticed in openSUSE 12.3 x64, KDE 4.10.5, Kaffeine 1.2.2. Tested with mp4 and avi files.
