qBittorrent official forums

Download qBittorrent ver. 2.9.7-1 from Ubuntu software center in Ubuntu 12.04 LTS.
Click qBittorrent in Unity the hard disk led flashes on-off a small window opens with icon and in a flash goes off but nothing else, I cant find the application.
How can I fix this. 

I have a similar problem. QBittorrent has been running perfectly for a considerable time - also on Ubuntu 12.04.
It will now no longer open though locked to Launcher, icon doesn't 'flash' when clicked.Attempts via Dash results in same situation.
Tried reinstalling, terminal output is:-
ray@ray-Aspire-5735:~$ sudo apt-get install qbittorrent
[sudo] password for ray:

qbittorrent is already the newest version.

Any suggestions please?

Open a terminal and launch qbittorrent from it by typing "qbittorrent". Paste here the console output.

Couldn't set environment variable...

HTTP user agent is qBittorrent v2.9.7

You could try using PPA, it is much newer version qbittorrent 3.0.6 and libtorrent 0.16.4...
I'm not sure if this would solve the problem, but it would still be a good idea to upgrade from 2.9.7
