Traceback:
 1: .Call(newuoa_cpp, par, ctrl, fn1)
 2: newuoa(initpar, optimft)

Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace
Selection: 

  I strongly suspect that the problem is with minqa, and
that loading rgl is just a way to make the problem surface.

  I may take a look at minqa , but you may want to send an e-mail
to the maintainer [ maintainer("minqa") ] as well ...
