F-Spot crashes when opened

Undupping from bug 437402 -- they do not sound like the same issue.

fspot crashes on startup when [new wave] theme is enabled.
included are two text files with bug information obtained using apport-cli and from running the program from terminal.
however, seeing that switching to [human] theme and starting the program worked as expected, i decided to import a folder with a few pictures as a test. no issues. then, still in the same session, i switched back to [new wave] while f-spot was still running, everything continued to work... i closed f-spot, tried running it again, and the program was still functional under [new wave]!
that being said, installing f-spot with the [new wave] theme enabled failed every time.

after my post above, i rebooted the system to check if it was some kind of coincidence but f-spot still seems to function without errors under the new wave theme. i even imported a large number of picture files without any issues..
what happened and why is it working now is beyond me. but the bug had been reproducible (for me) in the past. i had uninstalled f-spot before because it would not start.
of course, i did not suspect changing a theme had anything to do with that until today.

Just tried it a few minutes back. Still crashes for me.

ramdisk - gnome-dev-memory - Mountpoint file:///media/ramdisk True True MemoryStick
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 7013 error_code 1 request_code 157 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.)
