Thread:Support/Bug in Special:Firststeps

I had opened a new account and was dropped into Special:Firststeps. When I reached the step to request translator permissions, I picked German as language and left the textbox below empty. After submission, I got an internal error: Interner Fehler Wechseln zu: Navigation, Suche Set $wgShowExceptionDetails = true; at the bottom of LocalSettings.php to show detailed debugging information. ("Interner Fehler" means "internal error"). I then tried again and entered something into the textbox: it worked without error. It's not clear what the textbox is for.
