software-center-gtk3 crashed with AttributeError in copy(): 'NoneType' object has no attribute 'copy'

Hi! Thanks for your bug report. The bug you describe has been fixed in the branch I have linked and should be available in the next release. Please continue to report any bugs you may find in software-center. Thanks again for your help!

Bug at Software center.
software center crashed while switching between 'every software' and 'progress' button.

Software center crashed after I clicked to Installed icon.

I fixed the problem just now
sudo emacs /usr/share/software-center/softwarecenter/ui/gtk3/panes/softwarepane.py
line 145
add
if self.filter != None:
state.filter = self.filter.copy()
else:
state.filter = None

I added the lines after line 145, but then Software Center didn't start.

Where exactly shall I enter the code?

def copy(self):
         state = DisplayState()
         state.channel = self.channel
         state.category = self.category
         state.subcategory = self.subcategory
         state.search_term = self.search_term
         state.application = self.application
         state.limit = self.limit
         state.filter = self.filter.copy()
         return state

     def reset(self):

Hi,
If you don't know how to write python code, it's probably best not to try modifying the code, as you will need to get the indents correct etc.
The issue has been fixed and will be available in the next software-center update, so my strong advice is to wait for that.

However if you are intent on fixing it before then, it's best to get the entire updated softwarepane.py file from here:
http://bazaar.launchpad.net/~kiwinote/software-center/tweaks/download/kiwinote%40gmail.com-20110826110015-fobea07so04vh5kv/softwarepane.py-20110705095105-hkqkaog02375crmg-28/softwarepane.py

Then copy it into your current installation (i.e. /usr/share/software-center/softwarecenter/ui/gtk3/panes/) using sudo. (I would make a backup copy of your existing softwarepane.py file first)
Note, this could break your installation temporarily and may also have other unintended effects so attempt it at your own risk.

cheers
Aaron

To copy worked fine.

Thanks/Per-Inge

software center crashed

It crashes on my system when switching to the 'progress' section while installing any package.

i downloaded a .deb with firefox and tried to open it with Software Center (automatically). SC crashed before opening a window

Thanks very much for your fix, kiwinote! Your branch is merged to trunk now and this fix will be available soon in the next development release of Software Center.

Crashed for me while switching from "all Software" to "installed" tab in Software Centre - running 11.10 beta 30/08 (64 bit) under virtualbox 4.1.2 (Windows Host)

Seems that the fix didn't work in my case; various movements between UI elements of the Software Center seems to cause this crash.

No version of USC containing the fix has been released yet. Please don't comment that the bug is still occurring, unless you are using a version of trunk later than when the branch was merged. Thanks.

Requesting a bugpattern as beta-1 will include this bug (the fix will be released immediately after beta freeze ends).

Crashed after I pressed the X to exit the program.

Crashed while installing a deb package but it kept running and installed the package.. seems as if you guys are aware of the issue..

Bug pattern is already in place, removing the tag, thanks!.

This bug was fixed in the package software-center - 4.1.21

This bug is definitely not fixed. I've upgraded to the latest beta release with the new package and whenever switching to the "progress" screen while software installs are running, this crash is occuring

Hi Richard, this fix actually was released after beta-1, and so is to be available as an update. Please look for the fix in Software Center version 4.1.21, which was uploaded just a couple of hours ago and so may not be available in the archives yet. Please give it a couple of hours and then check for it with update-manager.

Thanks!

It also crashes when you try to update sources to install VLC on the live disk.

Crashes 11.10 Beta when installing various .deb in a row (mplayer dependencies). Downloaded .deb in Firefox, running them 1 at a time in Software Centre.
