hg out --debug shows

hg out --debug
all_dirs: _parse called with args ['out', '--debug']
all_dirs: _parse found another command outgoing
comparing with https://kalthad@bitbucket.org/kalthad/repo
using https://bitbucket.org/kalthad/repo
http auth: user kalthad, password not set
sending capabilities command
http authorization required for https://bitbucket.org/kalthad/contflowmap-einstein
realm: Bitbucket.org HTTP
user: kalthad
password


But the password *is* set.

What is wrong there?
