As well at rev. 105925

In my particular case, this bug makes itself know via:

Bug: "Cannot convert type `lambda expression' to `System.Action'"

    ./Async.cs(143,29): error CS1502: The best overloaded method match for
`EeekSoft.Asynchronous.AsyncExtensions.Run(System.Collections.Generic.IEnumerator<EeekSoft.Asynchronous.IAsync>,
System.Action)' has some invalid arguments
    ./Async.cs(189,30): (Location of the symbol related to previous error)
    ./Async.cs(143,29): error CS1503: Argument 2: Cannot convert type `lambda
expression' to `System.Action'


This bug makes itself known on recent SVN revisions but -- strangely --
compiles just fine on 1.9.1
Compiles as expect on MS.NET

Steps to repro:  Using recent SVN revision,

    svn co
http://nuxleus.googlecode.com/svn/trunk/nuxleus/Source/Nuxleus.Extension.Linq/
    co Nuxleus.Extension.Linq
    gmcs -t:library -recurse:*.cs -r:System.Xml -r:System.Xml.Linq
-out:Nuxleus.Extension.Aws.dll


Expected results: As per release 1.9.1,

    $ which mono
    /usr/bin/mono
    $ mono -V
    Mono JIT compiler version 1.9.1 (tarball)

            GC:            none
            SIGSEGV:       altstack
            Notifications: epoll
            Architecture:  amd64
            Disabled:      none
    $ gmcs -t:library -recurse:*.cs -r:System.Xml
-r:/usr/lib/mono/3.5/System.Xml.Linq -out:Nuxleus.Extension.Aws.dll
    $


Actual results: As per SVN 105925 (tarbal)

    $ which mono
    /usr/bin/mono
    $ mono -V
    Mono JIT compiler version 105925 (tarball)

    $ gmcs -t:library -recurse:*.cs -r:System.Xml -r:System.Xml.Linq
