  $ rm *
3. Launch the Ubuntu Software Center.
4. Select menu item "File"->"Sync Between Computers".
5. In the list view that is shown, expand one of the categories that includes one of your purchased items (generally, "Games" will work).

It crashed (several times already, not just with this particular flow) when using the awesome 'Sync between computers' feature and waiting for the list of apps of the computer I was comparing to, to be refreshed (it seems to auto-refresh every minute or so which is pretty irritating).

And I just got this on another machine as well (with updates applied on April 14), using the same steps.

I notice this bug is now the top crasher on errors.ubuntu.com. Is any sponsorship needed to get the fix landed in quantal/precise?

Hi Steve. This fix for this one went out to SRU yesterday for Precise with software-center version 5.2.2, and will be included in our first release for Quantal which should be very soon I expect.

Thanks!

Hi Steve, once this goes in as a SRU into precise-proposed it should be copied into quantal too.

Yep, noted. We are trying to be more strict about not doing copies from
-proposed to the devel release - it's ok in this case because
software-center is pure python and there's no new version of python in
quantal, but going forward please do separate uploads to precise-proposed
and quantal.

Hello Brendan, or anyone else affected,

Accepted software-center into precise-proposed. The package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!
