I really don't care much about using git gui clients, but I think they're useful when you need to visualize local network graphs.
That's the only reason I installed it in my work machine. And it messed up and erased my global user (name and e-mail) config. Uninstalled it and installed it again to see if it was something I did wrong and it was not: I was forced to rebase my commits and lost time doing it.
So, my question is: why does it need to erase a previously just fine git installation? Or is it a bug?
