We get this warning only when the category "command-line-validator" is empty. In this case, nsCategoryManager::EnumerateCategory returns the result of NS_NewEmptyEnumerator which is implemented by EmptyEnumeratorImpl. The C++ class EmptyEnumeratorImpl inherits from nsIUTF8StringEnumerator but doesn't implement QueryInterface for this interface, thus causing the warning. This is covered by bug 451501.

Fwiw, http://tinderbox.mozilla.org/showlog.cgi?log=SeaMonkey/1234009380.1234010085.6529.gz&fulltext=1 Linux nye Depend bloat on 2009/02/07 04:23:00 (Oldest log available:) It seems this warning went away long before bug 451501 fix... [Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.9.2a1pre) Gecko/20090409 Minefield/3.6a1pre] (home, debug+options) (W2Ksp4) (http://hg.mozilla.org/mozilla-central/rev/cb053a66c9ed) + [Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.9.2a1pre) Gecko/20090409 SeaMonkey/2.0b1pre] (experimental/_m-c_, home, debug default) (W2Ksp4) (http://hg.mozilla.org/mozilla-central/rev/cb053a66c9ed +http://hg.mozilla.org/comm-central/rev/b08051438f9f) I can't reproduce with this changeset just before bug 451501 push. Anyway, V.Fixed :-)

As I said in comment 2, this warning is reproducable only for applications that don't have any command-line-validator component registered. A quick search shows that Firefox, SeaMonkey and Thunderbird have some: http://mxr.mozilla.org/comm-central/search?string=command-line-validator I guess before the fix you could only reproduce in Sunbird (this bug blocks the Sunbird startup noise tracker) and Instantbird (the reason for which I fixed this).
