I wouldn't say it's a "strange" thing.  But it's a damned annoying one.  It
appears to be intentional, and related to Network Manager, and the "network
status daemon" and possibly the "DNS-SD Service Watcher".  They're  b0rked,
and I haven't seen any indication that there's a plan to fix this.

In KMail, I suspect it's _specifically_ related only to IMAP folders.  Since
all my mail is on the local IMAP server, so I shouldn't need _any_
interfaces up, that's infuriating.

Yes.  That's exactly true.

Yes, same error.

Oh?  That's news to me.  Thanks.
