Updating portage 2.2 from rc41 to rc42 caused a Python backtrace for me: >>> Installing (1 of 1) sys-apps/portage-2.2_rc42 * Cleaning orphaned Python bytecode from /usr/lib/portage/pym ..

This doesn't seem like it should have happened. I'm not sure what could caused it. If anyone can reproduce this then please comment.
Maybe this has been fixed by now. Please re-open if it happens again.
