notes colliding with key signature

[Jim Long]

I'm currently at a loss to find or Google a reference to a bug
tracker issue I'm aware of where note columns might collide with
key signatures under certain conditions.  No wait, it's at:

http://code.google.com/p/lilypond/issues/detail?id=2802

I have a piece in the key of C where some systems begin very
close to the clef.  Is this a case of colliding with the key
signature of C major?

The attached .PNG shows a bad case on the first system, and a
good case on the second.  If knowledgable folk think it's
obviously the same thing, I won't bother reducing my code to a
tiny example.

I do have other examples of the OP, if that helps.  One case is a
lead sheet where << chords melody >> is fine, but when I add a
rhythmicStaff in between, I get note-column/key-signature
collisions.

An update on the general status/difficulty of the issue would be
appreciated, time permitting.

Thanks,

Jim
