Hi Neels,

I think, this happens due to the following change:

22bc45b8bfb8d0f2d8a46c6e945f3b4388fdced0

since which every application does install default
commands by default, including 'exit' and 'end'.

At the moment there are the custom 'exit' and 'end'
commands in the OsmocomBB/mobile/vty_interface.c.
So, the crash happens because it attempts to install
already existing commands.

I've prepared a fix for that, have a look please:

Also, I've fixed one more thing by the way:
