preferences opened from systray don't open on current workspace
when the main window of gajim is say on workspace 1 and you are currently on workspace 2 and you r-click on the systray icon and chose "preferences", then the preferences window is opened on workspace 1. when you now select preferences again, it is shown on workspace 2. this occurs, when the window is not minimized or in the tray.
When gajim is minimized and you open the preferences, the pref window shows up on workspace 1 in the pager only, but is not on the screen. when you click on it either in the pager or in the taskbar, the window is visible. However, it is not in minimized state before it gets selected. Again, be on another workspace than the one gajim is on when doing this. If you are on workspace 1 and chose prefs in the systray on workspace 1, the prefs window is shown correctly.
when gajim is minimized to the tray, everything works fine on all workspaces.
