Larry, have you seen something like this before? The 3.1.9-1 kernel does not contain the patch from bug 728740, but we are using the compat-wireless drivers from 3.2.

The patch to fix that problem was recently merged into the mainline kernel as commit d90db4b. As it was marked with a Cc to Stable, it should be backported. Your compat-wireless choice is likely too old. The patch has been in wireless-testing for some time, and will be in the bleeding-edge version of compat-wireless.
I made a few changes to applications in the Kicker menu (Right click Kick Off Application Menu and select Edit Applications). When I saved these changes the system crashed. Package: kernel OS Release: Fedora release 16 (Verne)
The commit Larry referenced in comment #3 went into 3.3-rc1. The 3.2.x kernels in Fedora are using the compat-wireless-3.3-rc1 release, so that should be included in there. If you see this bug again with a 3.2.7 or newer kernel, please reopen.
