Unfortunately, right now there is no package with debug symbols for 1:2.22.1-0ubuntu4.1 version of gnome-control-center. So I have downgraded it to 1:2.22.1-0ubuntu4. The same behavior.
However, this is kind of tricky because the program doesn't crash, it just freezes for a second. I've attached result of backtrace (I followed exact instructions from wiki). ** Attachment added: "gdb-g-a-p.log" http://launchpadlibrarian.net/14100434/gdb-g-a-p.log -- Handling large list of wallpaper images in Appearance Preferences dialog freezes the window https://bugs.launchpad.net/bugs/225862 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
