[issue3115] TracMercurial hook is not working

[belidzs]

New submission from belidzs <balazs.keresztury at gmail.com>:

I'm using TortoiseHg 2.2 with mercurial 2.0 on client side and hg 1.4.3 on 
the server side with ubuntu 10.10lts and Trac 0.12. I've set up Trac and 
TracMercurial to hook my commits so linked bugs will be automagically marked 
as fixed.
I'm trying to push changes to my server, but the following message comes up:
(In spite of the message, the push is complete, without the hook)

% hg --repository D:\Documents\Visual Studio 2010\Projects\Aperitif push 
ssh://belidzs@10.35.35.27/hg/aperitif
pushing to ssh://belidzs@10.35.35.27/hg/aperitif
