Right clicking a tracker in the tracker-tab of a transfer will crash Tixati (64bitbuild) every time on linux (64 bit lubuntu).

I had the same problem (Kubuntu 14.04 LTS 64bit), stopped all torrents, exited and backed up .tixati folder containing the .dat files. Ran tixati-2.14-a1.linux-64bit, started to seed some torrents, clicked to select tracker in trackers tab, and Tixati just exited, went back to using Tixati v2.12.
