[gmime-devel] Segfault when parsing invalid address list (spaces in addresses)

[Damian Pietras <daper daper net>]

The current gmime version (from git) will crash if there is an invalid
white character in an address like this one:

To: sdfsdf wp pl,s sdfsaf wp pl,t sfsdfec op pl

It will read past the buffer. I've attached a simple patch to fix this
bug.

Poprawka segfault przy parsowaniu listy adresow, ktora ma biale znaki w adresie np.

To: sdfasf wp pl,c tert wp pl,sffdg rtre op pl
