Frank,


Thankyou for your response.

I cannot even get to that point because the call hangs.  I did a bit more
inspection (failing to notice before that it was using 100% of my CPU
time!).

A GDB backtrace from where it hangs:

I am rather confused at this point.  Any ideas would be most appreciated.
