Mercurial push, abort: authorization failed

I'm having problems with pushing to mercurial repository:

$ hg push
pushing to https://user:***@hg.domain.com/X_repo
searching for changes
abort: authorization failed

The same URL (with the same credentials) is accessible through the web browser. Also, I tried it without embedding usr+pass into the URL.

HTTPS is correctly configured, I tried both Basic and Digest auth -- without a luck.

Pulling (through HTTP) works fine.

I'm using hgwebdir to serve my repo.

What else should I check?

I found this: http://code.google.com/p/support/issues/detail?id=2580 In my case it's not random, it happens every single time.

Relevant part of my vhost conf:

  WSGIScriptAlias  /  /home/(...)/hgwebdir.wsgi

  <Directory /home/(...)>
    AuthType Basic
    AuthUserFile /(...)/basic-password
    AuthName (...)
    Require valid-user

    Order deny,allow
    Allow from all
  </Directory>

$ hg -v
Mercurial Distributed SCM (version 1.0.2)

Strangely enough hg outgoing works ok:

$ hg outgoing
comparing with https://hg.domain.com/X_repo
