Backport of 1.5:

Under Jaguar it seems that 'errn' return value keyword parameters don't
(or don't always?) show up with missed(). I think this is a bug in
Jaguar, but as it is a potential dangerous problem (the OSA event has
failed, but the Python code isn't told about this and happily continues)
this is a quick workaround.
