The first problem is from Empathy, the substitution Pidgin as an IM client. I got "Network error" when I tried to login my MSN account. I solved this issue by
but still feel uncomfortable with its user interface. Maybe I should give Emesene a go or stick with Pidgin.
Another problem is I could not mount my NAS using SMB/CIFS. I got a message box says
Unable to mount locationIt turned to be a keyring related defect. My workaround is deleting all the smb entries in Password: default group in Passwords and Encryption Keys.
DBus error org.freedesktop.DBus.Error.NoReply: Message did not receive a reply (timeout by message bus)
In my case, it's not a fresh install or an upgrade. Maybe that's the root of the 2 problems I encountered. To be a good trouble shooter, you have to be a good trouble maker.
