LinuxQuestions.org - Problem with bazaar

I'm trying to merge back the changes I made in my "eclipse" branch to my "stable" branch, but I get an error on bazaar:
Code:
$ bzr merge /home/antoranz/bus/eclipse

+N  doc/Cities/Bogotá/

+N  doc/Cities/Bogotá/TransMilenio A.png

+N  doc/Cities/Bogotá/TransMilenio B.png

 M  web/server/includes/city/ProcessedCity.php

I removed the lock and reverted the changes and tried again and I had the same problem. Is it something I should report to the bazaar developers?

Thanks in advance.
