This can happen with any of my launchers (I only have seven of them :
aoss firefox %u ; amule ; gksu /usr/sbin/synaptic ; xsane ; gimp-
remote-2.2 %U ; vmplayer ; gedit %U), but you have to combine at least
two "right-click > properties > close" actions.

The hang above happenned with the deadly "firefox-synaptic" sequence. It
won't happen if you repeatedly open/close the properties dialog-box of
the same launcher.
