1. what command are you running to start the merge?  Can you describe
the steps so that others can repeat it?

2. From our documentation:

   If Emacs reports an error, backtraces can help us debug the problem.
Type "M-x set-variable RET debug-on-error RET t RET". Then run the
command that causes the error and you should see a *Backtrace* buffer
containing debug information; send us that buffer.
