gnome-app-install crashed with AttributeError in itemIsInstalled()

[Cody A.W. Somerville]

Binary package hint: gnome-app-install

In Firefox, I clicked Tools > Add-ons and then clicked "Get Ubuntu Extensions". An interface similar to install/remove popped up and then apport popped up reporting this crash. The "Install/Remove Extensions" remained but the loading dialogue is frozen and says "Loading System...".

This happens for me as well: When I try to open an mp3 file with Totem, it wants to search for a codec to play the file. If I allow that, a progress dialog appears ("Nach geeigneten Codecs wird gesucht"), and the app-install window comes up. The progress bar reaches 100% but the progress dialog does not disappear, instead the crash report dialog shows up to report an error with the same title as this bug report. The app-install window is unresponsive (though it does redraw itself) and can't be closed normally, so I shot it with xkill.

Repeating the steps of the original reporter causes the same bug for me as well. My machine is an Eee PC 901 (x86-32), 2GB Ram, karmic alpha with recent packets (updated 1hr ago) installed on an SDHC card.

It has no relation to firefox as far as I can tell. I'm getting the error multiple times running "add/remove" from the applications menu. Each section (accessories, graphics, internet, etc.) produces an error as the "gnome-app-install" window's progress bar progresses.

I guess I'll just use "sudo apt-get" in a terminal for now : )

Some aditional info:

I started it from the CLI "/usr/bin/gnome-app-install" and that spat out a nice list of repeating errors :

Traceback (most recent call last):
  File "/usr/lib/python2.6/dist-packages/AppInstall/Menu.py", line 243, in _visible_filter
    self.itemIsInstalled(item):
  File "/usr/lib/python2.6/dist-packages/AppInstall/Menu.py", line 419, in itemIsInstalled
    return (self.cache.has_key(item.pkgname) and
AttributeError: 'NoneType' object has no attribute 'has_key'

to end with :

/usr/lib/python2.6/dist-packages/AppInstall/AppInstall.py:1248: GtkWarning: gtk_tree_model_sort_set_sort_column_id: assertion `tree_model_sort->default_sort_func != NULL' failed
  item.applications.set_sort_column_id(-1, sort_type)

I took a look at /usr/lib/python2.6/dist-packages/AppInstall/Menu.py which made me realise something. The last time I ran "Add /Remove" (software) from the gnome menu I selected the filter to show only installed programs. This filter is used again the next time gnome-app-install is run and is where I think things go wrong.

            if not self.activationStyle.isApproved(

                return False

                if rank == None:
                    return False
                else:
                    item.rank = rank
        return True

I hope this helps : )

For others who are confronted with this bug :

In http://ubuntuforums.org/showthread.php?p=7722188#post7722188 wayne_cat provided me with a solution to get gnome-app-install working again.

Run "gconf-editor"
Go to "apps > gnome-app-install"
Change the value of "filter_applications" from 6 to 0

I will have to learn tousand things. English of course too.
But I don't have much time. This is my problem.
Thx

Thank you for reporting this bug to Ubuntu. Karmic reached EOL on April 30, 2011.
Please see this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases

I've tried recreating this bug with Oneiric and was unable to, given the information you've provided. Please either a) upgrade and test or b) increase the verbosity of the steps to recreate it so we can try again.

Please feel free to report any other bugs you may find.
