Somehow I ended up with an empty content-prefs.sqlite.  This caused me to see this error every time I opened a new browser window:

Error: [Exception... "Component returned failure code: 0x80004005
(NS_ERROR_FAILURE) [mozIStorageConnection.executeSimpleSQL]"
nsresult: "0x80004005 (NS_ERROR_FAILURE)"  location: "JS frame ::
file:///builds/trunk/obj/firefox-debugopt/dist/bin/components/nsContentPrefService.js
:: ContentPrefService___dbMigrate0To2 :: line 756"  data: no]
Source File:
file:///builds/trunk/obj/firefox-debugopt/dist/bin/components/nsContentPrefService.js
Line: 756

It seems like the code was trying to migrate and repeatedly failing.  It seems like we should be able to recover from the file being empty (which could perhaps happen if the disk is full).

Indeed we should.  We already do for some cases of corruption; we should do so for this case as well.
