OK, I can recreate the problem now. The Snipppets plugin is not enabled by default. If I enable it I get the same behaviour you reported. If you run Gedit from command line with Snippets enabled, you can see it spewing errors. Evidently a bug. Looks like it's not a SLED specific one.

Can you raise a Service Request about this? If not you can use the Report a Software Defect (bug) form at https://www.suse.com/support/report-a-bug/
