Quassel IRC

In quassel, i somehow renamed one an individual who private messaged me. The core issue is when I went to interact with someone via double clicking their name, I somehow did something else....and i ctrl-v'd, and entered a mode to "rename the user", and I basically basically submitted a paragraph of text for their name that was in the paste buffer instead of a normal nickname of normal size..........
So now if i try to right click that name............to rename it back to their real name.........it crashes the app, because the app seems that it doesn't know how to handle a lot of text?

I attached "snippit.jpg"
where it shows <pistdov> atsecure, do you

It doesnt show the whole buffer, but that is the problem.
The text for the username is to long?

I'm using: v0.10.0 dist 575f2fe protocol 10 build mar 28 2014
