...

for the records, since i got the same after upograding to 10.X,
i decided to investigate more on the problem, and i found out
that things go bad when i login into my chrome account
and chrome starts downloading extensions from my other
(unvoluntarily synced) chrome instances.
Errors before the crash are the same pixman bugs i was seeing before:

	> *** BUG ***

Disabling the app synchronization at least stops the panic.
I have no idea what extension is giving trouble but i notice
that right before the panic the 'Hola' icon appears
(i have other things on my mac and Linux, including google drive,
hangout and probably other extensions not supported on FreeBSD).

One extension that is also active (the icon appears on the
menubar, but not on the list of extensions) is "Hola",
which has way too many permissions. I am not sure that is
the culprit though.

Anyways, for the time being the crashes are blocked.

This said, they should not occur in the first place so there
must be some underlying problem that needs to be addressed.

cheers
