I am getting a error window stating LAUNCH ERROR while trying to open other partition (ntfs , ext4) from desktop with description as follows.

Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

My network connection is working properly and it is couple of days Fresh installation alongside Ubuntu 12.04 Also posting a screen shot, though not a major problem but now i am getting it quite often.

enter image description here

P.S : I am guessing it is Mostly related to file manager [ thunar 1.2.3]
