I have posted this in the forum (http://bbs.archlinux.org/viewtopic.php?id=35175), but there was no answer, so I post it here as a bug.

Description:

After an upgrade (pacman -Syu, Arch was about 2 months old) running mozillaqs breaks KDE's "Run command" dialog.

When KDE is just started everything works as usual - Alt-F2 calls "Run command" dialog, it appears and runs commands. But after starting mozillaqs pressing Alt-F2 (or calling "Run command" from the K menu) makes dialog to pop up and immediately close. It does not appear after, neither by pressing Alt-F2, nor by calling it from the menu. It does not begin to work if I kill mozillaqs later.

Looks like mozillaqs startup affects any application that has icon in the system tray (or, better say, any application that has no tab displayed on the panel), and looks like this problem is not related directly to mozillaqs, probably this is some system tray icons displaying problem.

When I start mozillaqs it launches, but gets no icon at the system tray, it is displayed as whitespace. When I try to maximize window of some application located in the system tray (i.e. Amarok or Kaffeine), mozillaqs' icon appears in the system tray as a little sheet of paper (default icon for application with no it's own one?), and application's window pops up and immediately disappears. After this I have no more chance to maximize the application until I right-click it's system tray icon, choose "Minimize", right-click it again and choose "Maximize".

Steps to reproduce:

1. Install mozillaqs
2. Run mozillaqs under KDE (whitespace instead of mozillaqs' icon should appear in the system tray).
3. Press Alt+F2 - "Run Command" dialog should appear and disappear, and mozillaqs' icon appears in the system tray as a sheet of paper.
4. Alt+F2 does not bring "Run Command" dialog back to screen anymore.
