Hi Clemens,

My fedora 15 machine has a video card that doesn't support the need acceleration for gtk3, so I probably can't duplicate things with gtk3.

How did you get the debuginfo packages? debuginfo-install? or manually install the debuginfo rpms? The debuginfo packages need to match up exactly with the binary rpm. They have to be from the same build. Could you do the following to list out all the cairo related packages:

rpm -qa |grep  cairo|sort

I suspect that the there might be a version difference there. Those other libraries are from other packages: pango and glib2. You should be able to install the appropriate debuginfo for those with:

debuginfo-install /usr/lib/libpangoft2-1.0.so.0.2904.0 /lib/libgobject-2.0.so.0.3000.0 /usr/lib/libpango-1.0.so.0.2904.0

Worst you can get the debuginfo file from http://koji.fedoraproject.org/koji/ and get the debuginfo packages if they are not in a yum repo.
