sftp freezes Nautilus

[Gnaural <gnaural users sourceforge net>]

For a few months, I've had a strange problem with 
Nautilus when used for SFTP-access to any remote
server 
from any of my Debian-running computers. (NOTE: I run 
it as "nautilus --no-desktop --browser" on a typical 
Debian unstable distro, kernel 2.6.15-1-686).

Basically, I can successfully SFTP to a any bookmarked

address like this:

sftp://gnaural banjo bob net

And then once that has succeeded, I can get to my home

directory by calling another bookmark like this:

sftp://gnaural banjo bob net/home01/g1/gnaural

However going to the latter bookmark directly (that
is, 
without calling the former bookmark first) will always

freeze Nautilus (requring me to "Force Quit" it).

That alone would merely be a nuisance -- and I've 
gotten used to it. But beyond that, I've noticed that 
even when connected successfully, it seems like every 
action (selecting a file, changing directories, and 
other similar things) is MUCH slower than it was a 
few months ago. (I notice the difference when I SFTP
to 
the same servers from an older, non-updated Ubuntu 
distro that doesn't exhibit this behavior.)

I have a feeling that the gnome-keyring may be one 
possible culprit: in general, it started asking for 
more permissions around the same time as the Nautilus 
glitch -- always asking two times to allow it access
to 
the keyring even to merely archive a folder in my
local 
computer's directory.

So, anybody have any insights to help me get to the 
bottom of this -- or even where to post my
observations 
(like, does this sound like a Debian, Nautilus, or 
Gnome Keyring bug?). Incidentally, I did submit a bug 
to Gnome Bugzilla a few weeks ago:

Thanks!
