freeze while installing package

[Frank]

While installing "Ubuntu restricted extras", the software center window became completely unresponsive, as evidenced by the window manager rendering its window to gray scale. Although I've waited for over 30 minutes, the progress bar remains stuck at about 60%.

I've included the relevant part of my syslog.

In the hanging state the main software-center process had 7 child software-center processes and 1 debconf-communi process.
