F-spot crashes with 'error checking orientation'

OK. Tried removing every mono-, cli- and gac-package from the system and re--install f-spot & tomboy from there. Also removed my f-spot database and all other relevant files, I could find.

When running f-spot the very first time, the window shows up and then promptly crashes:

The program 'f-spot' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadRequest (invalid request code or no such operation)'.
  (Details: serial 978 error_code 1 request_code 153 minor_code 19)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

I then run f-spot a second time, to see if it repeats. It doesn't, as f-spot starts up just fine. BUT when I click the "add photos", it crashes:
