When I log in, all my plasmoids on the desktop (not on the panel) are misplaced - they appear on left upper corner of the desktop.

When I unlock widgets, all the plasmoids move to the proper (configured earlier by myself) places. When I lock the widgets, plasmoids stay on their proper places. I have upgraded my kde4 some times, but it does not help.

There is no such problem on my home PC with similar configuration, openSuSE 11.1 with kde 4.2.0 too.
