anaconda: possible recursive locking detected



During my last attempt at installing rawhide I got the following in the anaconda.log:

08:10:17 INFO    : moving (1) to step installpackages
08:10:17 INFO    : Preparing to install packages

It takes about an hour to finish filling the anaconda.log with package info like above. Then the download begins. It might have to do with:
