KDE4.6.3: Plasma panels settings mangled after restarting

[Andrej Kacian <andrej+debian@kacian.sk>]

Hello all,

I have recently upgraded to KDE 4.6 on wheezy, and I'm pleasantly surprised at
how much faster and less buggy the environment is.

However, among few bugs which annoy me is that after I set up my panels the
way I want them, KDE keeps changing their position and settings after I log
out and log back in.

State after login just now: http://bayimg.com/DaiPIAadi

The way it was before: http://bayimg.com/DAiPjAAdI
(the bottom bar is aligned to the left, wide only for the three icons and set
to autohide, so it's not visible)

Is there anything I can do to make this stop (apart from filing a bug) ?

TIA,
