Weird config problem with metacity in 2.6

[Kevin Oberman]

After I upgrading several systems to 2.6, I ran into an odd problem with
metacity configuration. On both other systems I edited the
/apps/metacity/general/action_double_click_titlebar to
"toggle_shade". But, on one system that key is a boolean! The action of a
double click is to maximize, the default in 2.6.

Any idea why this happened? And, more importantly, how can I get things
back to normal? I can't seem to edit the key to change it's type and I'm
still looking for where it comes from.
