I have run into similar issues I think. I've had to put print
statements in cobbler's python code to figure them out. I've found that
cobble templater's error reporting often stinks. But it's also possible
I'm not that familiar with python's stack dump.
Take a look at what is in the dhcp_tags list and possibly how your
ethernet/MAC addresses are defined. I've seen cobbler fail like this
when it looks for a value for parameter that isn't defined properly. I
ran into something similar with the suddenly missing if-gateway
parameter a while back.
Just a guess mind you.
Someone else might be able to help more, I'm just kinda stabbing in
the dark here. Do you have "net0" defined somewhere in your
/etc/cobbler/settings ?
