Description of Problem:
Runtime fails on generic method invocation.

Steps to reproduce the problem:
1. Compile gmcs t.cs

class C <A> {
  public static void foo<B> (C<B> x)
  {
    D.append (x);
  }
}

class D {
  public static void append<A> (C<A> x)
  {
  }

  public static void Main ()
  {
    C<object>.foo<int> (null);
  }
}

2. run  mono t.exe

Actual Results:

** ERROR **: file metadata.c: line 1812
(mono_metadata_parse_generic_param): assertion failed: (generic_container
&& (generic_container->is_method || generic_container->is_signature))
aborting...

It's a blocker.

It is caused by
http://galactus.ximian.com/pipermail/mono-patches/2005-June/060134.html
that I guess fixed something else :-)

I did some debugging and it seem that in
loader.c:504 the 'context' contains:

(gdb) p *context
$2 = {container = 0x8274d68, gclass = 0x82770f0, gmethod = 0x8277700}

Which probably isn't valid. Even if it is valid, the contex should
actually point to context -> gmethod -> container, which is a correct
context at this place.

I attach a little hack, which allowed me to go forward and workaround
the bug in some sense.
