Good to hear it's a bug. I thought this was normal for
Nautilus as it seems to do this on all our systems. I ran
strace -p and it seems to be doing the same things over
and over. I've attached one complete loop of the strace
results (it's a 10k attachment - I hope that isn't a problem
for the list). I looked through the listing and it does seem to
be busily doing all sorts of stuff but I don't know what
it should be doing so maybe someone on the list can have a
look and tell what might be wrong. Thanks!
