This problem is easiest described with a picture (to be attached). If you look at the picture, the menu that pops up on a right-click is too wide compared to the text entries in the menu. This only happens if "Grouping: do not group" is configured in the task manager settings, seemingly since the "Do not allow this program to be grouped" option dissappears, which otherwise would make the menu entries wide enough. I get this on KDE 4.3.1 and 4.3.3, but I don't get this on Kubuntu 9.10 (Karmic Koala) which also uses KDE 4.3.1. I've tried this with a completely new user, i.e. a fresh .kde4, but it would be good if someone could try to reproduce it so we know it isn't due to something I've done with my KDE installation, whatever that might be.

I just upgraded all qt packages to 4.6.0 (from 4.5.3) and that made the bug go away, so it seems this is a qt bug. For the record, when I installed kde4 (once it was marked as stable) I think I didn't have this bug. That was with qt 4.5.2, so perhaps it could be that it appeared when I upgraded qt to 4.5.3, and hence the bug is only present in 4.5.3?
