I think I narrowed this down to the following commit:

commit 5c854d7ca64df766c581c9ed7ff81e04c9d1fa4d
Author: Chris Meek <cmeek@redhat.com>
Date:   Wed Jul 13 10:31:47 2011 -0400

    PR12890: Renaming modules in Staprun

Although it is somewhat hard to say, because it doesn't always fail. But
I have never seen it fail before this commit.

Still trying to understand the real issue and the testcase though. So
all help appreciated.

Cheers,

Mark
