[Evolution] Forward and Reply hang

[Reid Vail <rsv869 runbox com>]

Hello Evolution user team

We are running Evolution 3.10.4 on Linux Mint 17.03.  

For the most part Evolution runs well but there are irregular but persistent
instances when "reply" or "forward" hang and the package needs to be killed and
restarted.  This has happened across several Mint releases and any help isolating the cause
would be greatly appreciated.

In case it helps, there is a lot of mail (1.5 gig compressed).  Also we're running
standard POP service.

Thanks

Reid
