Oh, I didn't know. Sory for the noise then...

Unfortunally I am not able to help with the debugging because some time 
ago I almost completely switched to Linux. Another thing is that my 
machine with 256MB of RAM is not able to compile monotone in any 
reasonable time with gcc :( [a lot of trashing]

I've converted to Mercurial and I had 2 main reasons:

1) not being able to compile monotone with gcc -- Mercurial is in Python

2) the need for custom 'server' and not being able to easily use one 
machine for multiple projects (one running instance of monotone handles 
only one database and I didn't want to put unreleated projects to the 
same database) -- Mercurial can export repositories over http using a 
Python cgi script (I can have as many different repositiories exported 
as I want) and any user with the right to execute cgi script can export 
repo without additional privileges
