http://ubuntuforums.org – When I double click the Home icon or click on the file browser (accessories menu) thunar takes along time open & it opens with the following warining : Code: 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. Thats the problem. (Hardware)
