[Users] Python plugin script errors: where?

[MJ Ray]

Does anyone know where the errors from python plugin scripts land? I
can't see them in the python console or xsession-errors and they'd be
pretty useful sometimes.

Maybe I'll go look for some GUI exception handler script...

Thanks for any help,
