Aw: Re: New panel in trunk

[Fabian Nowak]

panel just crashed after having inserted misspelled item
xfce-settings-show and tried to execute. after restarting the panel, the
launcher was still there and popped up the expected dialog when
executing.

hehe, same happens when inserting a new item with invalid command into
launcher.

got the impression you check for unknown commands only when reading the
config files?
