This crash seems to happen alot now: 

Application: Google Mail (jshand2013) (akonadi_imap_resource), signal:
Segmentation fault.

i have included my complete settings for the pim and kontact system, just to
see if my current settings are to blame.

what i can see so far:

in my imap settings it is set to download new emails every 5 minutes.  there
may be a clash here where you check with the main check button in kontact.  it
is know to crash here.

if i can think of anything else i will put it in here
