Yes, it definitely sounds like a bug :)

That was caused by a kernel patch that disabled polling of the MMC until
the MMC cover is closed. (That makes sense to save power, but prevents
usage of full-size MMC.) I'm not sure if the same patch is coming to the
sales release.

Hmm, I think the warning dialog could be quite annoying when the cover
is open and you use a full-size dialog :) (However, you can always do
'/etc/init.d/ke-recv stop' to disable all automounting logic.)
