I confirm the report on Precise and trying to remove other packages.
Nothing happens when clicking on 'remove' then after a while (~2 minutes) the following message is displayed on the console

2012-01-02 14:57:05,018 - softwarecenter.backend - WARNING - _on_trans_error: org.freedesktop.DBus.Error.NoReply: Message did not receive a reply (timeout by message bus)

Hello folks, thanks for your report! So, I am unable to reproduce this error with today's updates in Precise (as of about 1pm EST), whereas earlier I did seem to be getting some dbus-related errors when using software-center. These seem to be gone now, and Banshee (and other test apps) can be installed and removed without issue on my machine.

Could anybody who is experiencing this bug please try again with the very latest updates in Precise? Let me know if you are still seeing it and I will dig in.

Thanks!

Hi Gary! Chris's aptdaemon fix[0] which was uploaded today fixed these issues for me and I have been using it for the last two weeks without any further issues.

Hi kiwinote, thanks for your note! I'll update the bug accordingly.

This bug was fixed in aptdaemon version 0.43+bzr756-0ubuntu1 in Precise.

aptdaemon (0.43+bzr756-0ubuntu1) precise; urgency=low
