I found some time to look at the code and it appears that the automatic
creation of labels for frames happens always.  There is no customisation
possible.  As this problem is stopping me from generating the slides I
need for my lectures *now*, I have removed the automatic label
generation, leaving the possibility of user specified labels.  A patch
is attached in case this is of more general interest. 

A better solution would be to have a variable to be able to customise
this behaviour, I imagine.

Thanks,
eric

Subject: [PATCH] Removed automatic creation of labels for frames in beamer
 export

* lisp/ox-beamer.el (org-beamer--format-frame) The options passed to
the frame command will include only labels defined explicitly in the
org file.  Automatic labels will not be generated.  It seems that
labels prevent beamer from processing other options, allowframebreaks
in particular.
