BUG message when toggling Tor on

Hey,

I just launched Firefox 3.5.9 on OS X, and got this message when I clicked torbutton:

Torbutton BUG: torbutton_setBoolPref failed for network.dns.disablePrefetch/dns_prefetch to value true: [Exception... "Component returned failure code: 0x8000ffff (NS_ERROR_UNEXPECTED) [nsIPrefBranch2.getBoolPref]" nsresult: "0x8000ffff (NS_ERROR_UNEXPECTED)" location: "JS frame :: chrome://torbutton/content/torbutton.js :: torbutton_setBoolPref :: line 845" data: no]

Torbutton version 1.2.5-pre11.

As far as I can tell browsing works as expected.
