Description Marcel Holtmann 2007-02-06 08:56:06 EST
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.
