	No, here's a patch to nnvirtual. Basically a line in gnus-start
was changed from (gnus-get-unread-articles-in-group info active) to
(gnus-get-unread-articles-in-group info active t) which caused the
problems.

	If you apply the patches, be sure to re-bytecompile the files.
And you need to entirely quit your emacs, don't try to reload them.
Generally various random nnoo madness results otherwise.
