  Sadly it recurred just now, and 'Leave Messages on Server' is still 
disabled.

More seriously, shortly after that when KMail received incoming emails 
they were shown (in Inbox) with *empty* Subject, Date, From, and To 
fields, with the Source of the message as the Body...
  (This included a test email that I sent to myself.)

However, after logging out and back in again, the situation has reverted 
to normal.

Has anyone seen such a thing before?   I haven't.

As KMail (1.9.10) was my main reason for trialling Trinity (3.5.13.1), 
I am becoming very uneasy with its stability*, and am considering giving 
up on Trinity - which I do not want to do..

(* I've noticed that KMail tends to misbehave immediately after the 
spurious "Unable to comoplete LIST operation' warning.)
