software-center crashed with AttributeError in get_maintenance_status(): 'Ubuntu' object has no attribute 'get_distro_release'

[Thomas A. F. Thorne]

I had opened software-centre and installed a couple of Twitter clients (Choqok and ttytter). I think I then closed software-center but I may have left it open. I went back to the application and searched for some qt5 packages. I already had qt5-qtmake installed so I searched for qt5 and got 1 result. I clicked more info on "U1Db QML Example Gallery" as that was the only result. It did not show me what I wanted to see so I left the Window and started browsing in Chrome. After a while I noticed this error pop up.

I might have done an `aptitude search qt5` in the background before or after I left the window. I cannot think of any other actions I have taken that would be related.

I was just bought to this page again after a software problem box popped up. I was not doing any of the things with Qt that I listed before. I had just left it installing clamav + docs when the error message popped up.

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

I am also seeing this error when trying to view 'more info' for the libboost-dev and ocaml packages in software center for Ubuntu 14.04. I get exactly the same traceback in the terminal.
