Comment 22 for bug 1109251

@bwat47, looks like it is the issue linked by zarquon42, although things are now working after latest round of apt-get updates so they might have fixed the gnome based gsettings bug that was causing the issue with pidgin. All my accounts seem to be good and well at the moment, with the exception of after the sleep/resume cycle, at which point pidgin hangs and the screen gets grayed out.
