When right-clicking on a launcher and selecting "Properties" in order to configure the launcher, I get a crash, see backtrace below. I have a two-panel layout (one hidden, one normal). This seems to happen only with the launcher, there's no crash when opening the properties dialog of any plugin I have (menu, tasklist, clock, show-desktop, keyboard-switcher).

The svn revision is 22438 (panel and all other components, except xfdesktop, which doesn't compile here atm).

Best,  Nick.
