segfault when right-clicking username and choosing "Talk" on IGS, Cyberoro

[fuloating]

Probably quite similar to #19

When I right click on a username on user list and choose talk, the qgo crashes. Linux console says: "QSortFilterProxyModel: index from wrong model passed to mapToSource
Segmentation fault (core dumped)"

I don't know how to get backtrack from the core, if that is needed here. I am also not sure of the commit version I am using. At least this is 2.1.0. It's already more than couple days when I downloaded the sources from this git, but I did the qmake, make and installation yesterday. This is on Lubuntu 14.04. And to note, I did not have this on 2.0.0 (from ubuntu repos), which I had couple days ago before installing 2.1.0 from git. On 2.0.0 it opened a new tab with this user on left panel along with shouts and messages.

The error message is in fact very informative. This error was indeed introduced in an attempt to fix #19. Fixed in d8433f3.
