[ZPatterns] ZPatterns 0.4.3p2 breaks LoginManager; 0.4.3p1 works fine

[Itai Tavor]

Hi Steve,

Wow, quick response. Thanks.

I'm not going to be able to upgrade to Zope 2.4 for a while, and I 
don't feel safe messing with SteveA's pathces... this is going into 
two live sites. Think I'll stick with ZPatterns 0.4.3p1 until a 
tested patch or fix exists.
