Cause
Mercurial is failing to clone a repository with too many open heads. See this and this page for more details. The list of open heads is causing a server error because of the large URI.
Resolution
Get the hosting administrator to increase the GET and POST size allowed on the server, or failing that, change to use ssh instead.
E.g. for http://bitbucket.org/mirror/liftweb, use the bitbucket provided ssh access, ssh://hg@bitbucket.org/mirror/liftweb.
