Not sure wether this is fixed in all 2.6.18 sources:

------- Additional Comment #8 From David Howells 2007-02-06 03:12 -------  
Okay... Found it: the key serial number collision avoidance code is wrong.

This didn't use to be a problem as the key serial numbers were allocated from 
a simple incremented counter, and you'd have to go through 2 billion keys 
before encountering a collision.

However, now that random numbers are used instead, collisions are much more 
likely.
