software-properties-gtk crashed with DBusException in call_blocking(): org.freedesktop.DBus.Error.NoReply: 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.

Status changed to 'Confirmed' because the bug affects multiple users.

Also treid to remove a repository -> crash.

Precise x64 (all updates installed)

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, this bug report is about a DBus client failing to connect with the DBus backend and to really understand the issue we need the crash from the DBus backend not from the client. Client crashes are prevented from being report by apport in Precise and in the event that the backend crashes apport should report those ass separate. Because of the previously stated reasons I am setting this bug report to Invalid.

I don't care if it crashed because dbus went away (which I don't think it's the case). I don't care if a meteor hit a canonical data center and some service went out. The client should not crash. For this reason I'm setting this bug as valid.

I agree with Shock. This should not happen. The code should be adjusted so this doesn't occur.

Kamran, what package version was this fixed in?

While I agree with Shock that this should be fixed, it still stands that this crash report from the client has insufficient information and we really need the crash report from the backend to be able to fix the root cause of the crash.
