Re: [Mibble-users] NullPointerException

[Per Cederberg]

Thanks for a great bug report! Makes life so much easier
when I get a minimal MIB that reproduces the problem.

Here is a link to the bug report:

http://savannah.nongnu.org/bugs/index.php?18843

As can be seen, it has already been resolved. I'll
release the fix as part of version 2.9.alpha1 later
today or tomorrow.

Cheers,
