At random, here is one from 2006: 
<http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=364953>

When I google for "Error while getting folder information"
I get reports going back for several years,
without, as far as I can see, any clear resolution or even explanation.

Well, it seems to occur equally often under courier-imap .

I have solved the problem in my case, without understanding it.

KMail appears to show a folder, College=>inbox=>uidvalidity
But I don't find any such folder anywhere in ~/Maildir/ .
I've no idea if this phantom folder should be present,
and if so what it means.

This folder had the setting, "Include this folder in mail checks".
After unchecking this box (which I did not check in the first place)
the problem goes away - I no longer get an error/warning
when I Check Mail in KMail.
