Icons missing from KDE4 system tray
I'm currently running Fedora 10 64-bit, with KDE 4.3 installed from the Red Hat KDE repos. It seems that recently (i.e., within the past couple days) something has changed that is now causing system tray icons to not be displayed properly for gnome or kde3-based applications (e.g., pidgin, gSTM, or knetworkmanager).
I just upgraded to KDE 4.3.2, although this started happening before that update with KDE 4.3.1.
Does anybody know what could be the cause? I hadn't rebooted my computer for a week or so, so any updates that came through over that time could be the source of the problem.
In any case, I've tried moving the .kde folder in my home directory to a backup location to see if it was a problem with the KDE configuration, but that didn't seem to resolve the problem.
Any suggestions would be really appreciated.
