r5992 - Crash on assigning vehicles to no route

[Foxglove]

Good evening.
I bought a new truck, and then, when I accidentally tried to press "Assign to this route" button in bus depot window while no routes were selected in "Route" field, the game crashed. I restarted and repeated my actions on purpose, and it crashed again.
Just thought I have to report it.
UPD. This all hass been done in multiplayer mode

Thanks for the report. Should be fixed in r5999.

Assigning no route to a convoy is important IMHO, so thank you for reporting. (and many thanks to Dwachs for fixing )
