Description of problem: Trying to run gnome-background-properties hangs for me. This is probably the first time I've run it since I upgraded to FC6. Version-Release number of selected component (if applicable): control-center-2.16.0-11.fc6 How reproducible: Seems everytime I run it. Here is the tail end of a gdb session with it. It prints the GdkPixbuf errors by the thousands. I finally just control-c'd it and did a backtrace: (control-center:13677): GdkPixbuf-CRITICAL **: gdk_pixbuf_composite: assertion `src != NULL' failed (control-center:13677): GdkPixbuf-CRITICAL **: gdk_pixbuf_composite: assertion `src != NULL' failed (control-center:13677): GdkPixbuf-CRITICAL **: gdk_pixbuf_composite: assertion `src != NULL' failed (control-center:13677): GdkPixbuf-CRITICAL **: gdk_pixbuf_composite: assertion `src != NULL' failed (control-center:13677): GdkPixbuf-CRITICAL **: gdk_pixbuf_composite: assertion `src != NULL' failed (control-center:13677): GdkPixbuf-CRITICAL **: gdk_pixbuf_composite: asserti---Type <return> to continue, or q <return> to quit--- Program received signal SIGINT, Interrupt.

This looks quite bizarre to me. Could you please reproduce the problem with the control-center-debuginfo, glib2-debuginfo and gtk2-debuginfo packages installed, and gather a backtrace again?
I have been seeing this bug for some time on my box running out of devel and just got around to having be annoying enough to find this BZ. I've added an attachment of a gdb session with the control-center-debuginfo, glib2-debuginfo, and gtk2-debuginfo packages installed. I don't know if this is what you need to see, but please let me know if you need different information.

Also, I guess this might help! :) $ rpm -q --queryformat '%{NAME}-%{VERSION}-%{RELEASE}.%{ARCH}\n' \ control-center glib2 gtk2 control-center-2.17.90-6.fc7.x86_64 control-center-2.17.90-6.fc7.i386 glib2-2.12.9-3.fc7.x86_64 glib2-2.12.9-3.fc7.i386 gtk2-2.10.9-3.fc7.x86_64 gtk2-2.10.9-3.fc7.i386 $ cat /etc/fedora-release Fedora release 6.90 (Rawhide)
Thanks Brenton, for the information. This might be my fault. At one point I had a buggy thumbnail patch in. I don't know if I fixed it before FC-6 or not. If not, I should grab it from the RHEL branch or from upstream and do an update.
I still see this with control-center-2.16.3-11.fc6.i386. Do you need another backtrace? If so I can install the debuginfos and get one.
