[Mono-list] [ MCS Fix ] expression.cs Patch

[yoros]

Hi,

Here I send a fix for a indexer bug in the inheritance. This fix is
tested in mono 0.19 and it works. In the current mcs from cvs there is a
problem with the Indexers but it is out of the file that I changed. The
patch is for "expression.cs".

I send a testcase too.

See you,
        
    Pedro
