I have installed the vidalia by following these instructions everything went as they mentioned. When I started vidalia it gave me the error:

Vidalia was unable to start Tor. Check your settings to ensure the correct name and location of your Tor executable is specified.

I found that bug here and followed their instructions to fix it and now after that

it says:

Vidalia detected that the Tor software exited unexpectedly.
Please check the message log for recent warning or error messages.

Logs of Vidalia

Oct 18 02:15:06.937 [Notice] Tor v0.2.3.25 (git-3fed5eb096d2d187) running on Linux.

Oct 18 02:15:06.938 [Notice] Opening Socks listener on 127.0.0.1:9050

Oct 18 02:15:06.938 [Warning] Could not bind to 127.0.0.1:9050: Address already in use. Is Tor already running? 

Oct 18 02:15:06.938 [Warning] /var/run/tor is not owned by this user (waqas, 1000) but by debian-tor (118). Perhaps you are running Tor as the wrong user? 

Oct 18 02:15:06.938 [Warning] Before Tor can create a control socket in "/var/run/tor/control", the directory "/var/run/tor" needs to exist, and to be accessible only by the user account that is running Tor. (On some Unix systems, anybody who can list a socket can connect to it, so Tor is being careful.) 

Oct 18 02:15:06.938 [Warning] Failed to parse/validate config: Failed to bind one of the listener ports. 

Oct 18 02:15:06.938 [Error] Reading config failed--see warnings above.
