In case you wanted more info, this is what appeared to be happening... (thanks to some of the IRC people for filling in the blanks!)
It cant connect to get the version number, so it grabs the one from the file.
This version number seems to be null
The chat then barfs trying to output a message that has a null in it.
Thats a guess, but its either that, or its dying just trying to get the version in the first place. Given that the top of the stacktrace is about chatmessages though, its probably a cascade effect of not being able to get the version number, rather than not being able to get the version number itself thats caused it.
*shrug* - the fix I posted above seems to have been confirmed to work so far.
