Comment 37 for bug 892316

I can confirm that the same thing happens with Rhythmbox and Clementine. It would seem that pausing playback switches the time elapsed to a total playback time, which resets if playback is restarted by stopping and restarting or by skipping tracks. It's somewhat unexpected, but I don't think it's too serious an issue. I honestly don't recall the extension doing it before the patches, but then again I never really did pay that close attention to it until recently.

It would definitely seem the issues I'm experiencing with tracks occasionally not playing properly and requiring playback to be restarted is related to something else on my LMDE installation, since Lisa did not show the same issues. Clementine also does not seem to be experiencing this problem, while Banshee (my normal media player) and Rhythmbox both do. I will have to run some tests with Banshee and Rhythmbox with the extension disabled to confirm for certain whether or not the extension may be causing the issues.

In any case, the specific bug this report was about seems to have been fixed. I'll keep you posted if anything else unusual related to this extension should arise.
