Bug Description

The crash happened during the refreshing phase (sth like apt-get update) after removing a source (PPA) from 'Other Software' and clicking 'Close'. This window appeared...

--->
The information about available software is out-of-date

To install software and updates from newly added or changed sources, you have to reload the information about available software.

You need a working internet connection to continue.

...and I clicked 'Reload'. The window went gray for approximately 3 seconds prior to the crash.
