I do know of one where the spoiler handle on a Grob 103
broke after they had been deployed and jammed full open, resulting in
an off-field landing.

And I know of a case where just one spoiler deployed on a glider. Causes a
nasty uncommanded roll. The only solution (once you figure out what is
going on) is to close the spoilers and proceed without them.
