I've setup two collections of repositories according to the manual http://mercurial.selenic.com/wiki/HgWebDirStepByStep#Current_version
My hgweb.config looks like this
[paths] /guide = /home/hg/guide/*
Then I created "tp" repository in the guide collection and manually configured hgrc.
Repo list don't recognize repo groups. Result is on the screen1.png. After click on "/dvs" link I got error (screen2.png)
Repo list created by hgwebdir.fcgi is ok.
