Hello,
Even after an upgrade to Cobbler 1.6.6 on RHEL5, I still had the
unicode bug adding "u" in front of profiles,repos etc...
I fixed this problem by upgrading python-simplejson to version 2.0.5
replacing EPEL RPM by rpmforge RPM (instead of 2.0.3).
Package here :
http://packages.sw.be/python-simplejson/ and then rpm -Uvh
Hope it helps,
