This is a problem that first appeared as soon as I upgraded between
versions. It has now happened again.

When changing servers, in a tabbed view, the list of subscribed groups
flashes on the screen and is instantly replaced with the following:

p.sendlater 0 0 
p.sent      0 0

Preceeding this problem I had been using Pan for several hours this
morning, all without incident. Restarting Pan clears the problem.

I am un-able to reproduce this fault, although this is now the second time
this has happened.
