change_set.cc:526: invariant 'I(j != p2.end())' violated

Hi,

when trying to propagate some changes from one branch to
another, I got this error:

  monotone: delta on vl_prog_fig2dev.m4 in first changeset renamed to 
vl_prog_fig2dev.m4
  monotone: change_set.cc:526: invariant 'I(j != p2.end())' violated
  monotone: db.execute("ROLLBACK")
  monotone: discarding debug log
  monotone: fatal: std::logic_error: change_set.cc:526: invariant 'I(j != 
p2.end())' violated

  monotone: this is almost certainly a bug in monotone.
  monotone: please send this error message, the output of 'monotone 
--full-version',
  monotone: and a description of what you were doing to 
monotone-devel@xxxxxxxxxxx

The complete --debug output is here:

Any help would be appreciated.
