Further investigation of this showed that I had a package called libwncksync-glib installed. The shared library /usr/lib/gio/modules/libgiodbus.so with the symbol lookup error is part of that package. gdm itself does not depend or link to any shared library provided by libwncksync-glib. Still this undefined symbol causes gdm not to start. I wonder if that's a design issue of GIO. Removing the package libwncksync-glib, which nothing depends on, solved the issue and got gdm back into working state.
