Bug Description

Note for Precise SRU:

This change has no effect in Precise. It is a simple removal of a single line that was an obsolete workaround for an old bug long since fixed. This line caused a crash in Quantal and so was removed there, and as it is dead code in Precise we removed it from here as well.

Regression Potential:

Software-center crashes when started
Ubuntu is fully updated with Quantal

Hmm, this seems to only be happening on Quantal? I can find no reports of this one in Precise to this point.

I'm creating a Quantal VM to test with.

Yes, I can verify that this crash occurs in my Quantal VM, today's build.

Looks like line 176 of /usr/share/software-center/softwarecenter/ui/gtk3/views/ is trying to call Gtk.ProgressBar.set_data(), which doesn't appear to be a valid method from what I see in the docs at

Forgot to add: Commented out line 176 and it works fine, though I didn't go look to see if the visual bug 606942 was reintroduced.

Gary Lasker (gary-lasker) wrote :

Hi 3vi1, and thanks for your comment. Indeed, that is the offending line and its removal is the fix waiting for merge in my attached branch. Indeed, this line was an old workaround for a bug in the light-themes package that has long since been fixed, so it is perfectly safe to remove. There is no visual glitch or difference at all when the line is removed.

We will try to get this fix merged and the fix released in Quantal ASAP.

Thanks again!

I can confirm this also happens in 12.04 AMD64. Software Centre (excuse the British English) tries to install then hangs & has to be force quit.

Bug reporter didn't work either.

This is on a brand new, clean install from Live CD on a HP du7200 2 x 2.8 GHz Intels with 2 GB's of RAM. I have another exact same machine running 11.10 AMD64 & there's no problem.

Hello userdce, or anyone else affected,

Accepted software-center into precise-proposed. The package will build now and be available in a few hours. Please help us by testing this new package. See for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you please change the bug tag from verification-needed to verification-done. If it does not, change the tag to verification-failed. In either case details of your testing will help us make a better decision. Further information regarding the verification process can be found at . Thank you in advance!

I have verified that software-center version 5.2.3 in precise-proposed causes no regressions and everything works as expected.
