...Conversion complete!

Command line is 

hg -q --encodingmode ignore convert --datesort --filemap filemap <path to
source repo> <path to target repo>                                         
                                                          
re-running with

hg --debug --encodingmode ignore convert --datesort --filemap filemap <path
to source repo> <path to target repo>                                      
                                

lets the conversion finish correctly. It seems that this code fails unless
it is executed in 'debug' mode.
