While playing a movie, totem shows the playtime inside the statusbar like this "XX:XX / YY:YY", when you use the scrollbar the text changes "Jump to XX:XX / YY:YY" (or something like that, in the german translation it's Zu XX:XX / YY:YY springen).

This change is a problem inside the fullscren mode, since it changes the length of the scrollbar. E.g.

1) You play a video in fullscreen
2) You point your mouse of the scrollbar and grab the slider
3) At this moment the text next to the scrollbar changes from "XX:XX / YY:YY" to "Jump to XX:XX / YY:YY"
4) This results in a shorter scrollbar than the one you had first
5) You are on a totaly different position inside the movie
