flameeyes is the fellow making all the fuss about this. On his blog

http://blog.flameeyes.eu/2009/12/01/gentoo-service-announcement-keep-clear-of-
gnu-patch-2-6

he gives a way to build a decent list that removes packages re-emerged since 
patch was downgraded again. The trouble with a bug like this is that it gets 
used everywhere and affects very basic packages which are then used by other 
packages (that may or may not have been patched meanwhile) potentially 
affecting their behaviour too.

The effects are complex and never fully determined. Consider this: rebuilding 
world on a modern desktop will take around 24 to 36 hours. You could spend 
more time than that figuring out how to build a full list :-)

It's certainly possible, the times certainly coincide. And you do have 
symptoms that no-one else is having (sorta the kind of thing you'd expect from 
a patch that should have been applied and wasn't).

It's worth downgrading patch and rebuilding X even if only to see what happens
