I believe 10d54e2 will fix this. Or, more like, work around the problem, since the invalid input should not cause a crash. Lets not close this bug until we understand what's happening there...

OK for 12.0.1 backport.

The fix does not apply cleanly, could someone backport this and push a branch to their local github fork?
