In a pinch, you can tweak your copy of the library while this gets
sorted out.

This looks perfect to me.
A little bit of time trapping
on key_register and key_unregister might explain what's up.
There should be one key_register and a matching key_unregister
for each exported type. Since this is very hard to reproduce,
could I ask you to spend a little time investigating why
this seems not to be true in this case? I would hope
that trapping on these two functions and watching what
the arguments are might shed light on the mystery.
