Comment 229 for bug 439448

I was regularly but not always affected by this bug and tried Mal's workaround from comment #223, adding separators around the session applet. Well, I have not experienced the problem for several weeks now. It also works with the session applet being in the right corner and just adding one separator to the left... Once I tried removing the separators again (still leaving space around the applet) but right on the first login after the next boot, the corruption reappeared, i. e. basically the problem is not solved, but this workaround seems to work.
