firefox problem

["Steven M. Bellovin" <smb%cs.columbia.edu@localhost>]

After upgrading to the very latest -current, I'm seeing

firefox-bin: Error detected by libpthread: Destroying condition
variable in use. Detected by file
"/usr/src/lib/libpthread/pthread_cond.c", line 92, function
"pthread_cond_destroy". See pthread(3) for information.

This is with -current from a couple of hours ago, and firefox 2.0.0.2
compiled from source about a week ago.  My userland is in sync with my
kernel.
