Version:           4.3.3-109.4.i586 (using KDE 4.3.3)
OS:                Linux
Installed from:    openSUSE RPMs

Every time I reconnect to WLM using kopete, my screen name is reset to "pvince81", which is the prefix of my email address. I always have to manually set it again to "Vincent".

I can see this because I added myself as a contact in the list.

In previous kopete versions the previous screen name was always kept, probably saved by the server.
Note that I didn't re-try the old kopete version, so it might also be a change on the server side. I just remember having upgraded recently from KDE 4.3.2 to KDE 4.3.3, and that's when this issue appeared.

I have two different computers, both running openSUSE 11.2, on which this problem exists.
