Just to save someone else some pain:
Bridging utilities (brctl) seem to seg fault on any use after upgrading the kernel to 2.6.6-1.427. I believe this renders bridging completely unusable after this kernel upgrade.
Kernel changelogs show a bunch of bridging work in the 2.6.6 -> 2.6.7 timeframe, and the bridge-util changelogs show similar tracking changes.
Upgrading from the bridge-util version Fedora ships (0.9.6, I believe) to the current version 1.0.4 fixed the problems for me.
I've filed a bug on this:
