The comment posted by Jochen Fahrner on 2010-12-30 was the perfect solution. Installing version 26.1 of glib2 from the maverick-proposed package worked for me and fixed issues with other applications that would not launch, in addition to the issue described in this bug report.
I'm new to Ubuntu, so I figured I'd type up what I did in case others came through here later looking for a solution and didn't understand the comments posted thus far. Follow the link Jochen provided (https://wiki.edubuntu.org/Testing/EnableProposed). Add maverick-proposed to sources. This is outlined in the link, but the simple way is: -- Simply open Ubuntu Software Center under Applications, click Edit -> Software Sources, enter your password, click the "Updates" tab, make sure that "Pre-released updates (maverick-proposed)" is checked/activated, and then click the "Close" button. Follow the additional instructions under the section of the page linked above titled "Selective upgrading from -proposed". Run "sudo aptitude -t maverick-proposed" and select "libglib2" under "libs" (which itself is under "Upgradeable Packages") as the package to update. The version will be 26.1. Instructions for browsing around Aptitude are provided in the link above, so be sure to read the section under "Selective upgrading from -proposed" for all the information you will need. That's it. After glib is updated, restart your computer and the issue should be gone. This solved several issues for me, so I'm very grateful. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/672873 Title: Installed GSettings schemas not detected on PowerPC -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
