[Evolution] Bug#579172: evolution hangs after some number of pop fetch cycles

[murf]

Hi,

I can confirm this bug. IMAP *does* work, but POP3 does not.

Here is a tcpdump log of traffic from client to server. The traffic stops, 
and evolution hangs with no progress on POP3 accounts, the progress screen 
says 'Waiting'.

(slightly edited log, I have 3 pop3 accounts, so I tried to strip out 
dupes)

cheers,
Damian.
