a worse execution plan than in 4.1 for some queries.
It happened due the fact that at some conditions the 
optimizer always preferred range or full index scan access
methods to lookup access methods even when the latter were much
cheaper. 
The problem was not observed in 4.1 for the reported query
because the WHERE condition was not of a form that could
cause the problem.
Equality propagation introduced on 5.0 added an extra 
predicate and changed the WHERE condition. The new condition
provoked the optimizer to make a bad choice.

The problem was fixed by the patch for bug 17379.

When a view statement is compiled on CREATE VIEW time, most of the 
optimizations should not be done. Finding the right optimization 
for a subquery is one of them.
Unfortunately the optimizer is resolving the column references of 
the left expression of IN subqueries in the process of deciding 
witch optimization to use (if needed). So there should be a 
special case in Item_in_subselect::fix_fields() : check the 
validity of the left expression of IN subqueries in CREATE VIEW 
mode and then proceed as normal.
