#5 licq window becomes unmappable

[Maciej Kalisiak]

Here's the order of operations that causes trouble (using waimea
v0.3.3):

- start up licq (an ICQ client)
- go to licq's Options and select "Use Dock Icon"
- (it nicely appears in the dock now)
- close the main licq window
- (it closes fine, the Dock App stays)
- left click on the licq dock app
- (the main licq window appears again, as it should)
- stick it so that it appears on all desktops (I have 3x3)
- close main window
- left click on the lick dock app (in the hope to bring back the
main window again)
- (main window is not visible anywhere now, although it does
appear in the windowlist; selecting it from there brings one to the
desktop where it was originally, but it is not visible there)
