The bug appears to have been introduced by the following
commit, which had some pretty far-reaching changes:

commit 2ce35292b9e96da38cb56878005aba20891689eb
Author: Peter Clifton <pcjc2@xxxxxxxxx>
Date:   Sat Apr 30 15:20:39 2011 +0100

    Convert board objects to GLists of g_slice allocated memory
    
    This enables pointers for these objects to be immutable during their
    lifetime, which is a _huge_ benefit for some operations.
    
    Having otherwise was becoming VERY tiresome, and was a perenial source
    of bugs tripping up novice and experts of the codebase alike.
    
    Due to the risks associated with modifying the structure being iterated
    over, this patch makes the relevant *_LOOP macros iterate over a shallow
    copy of the underlying GList. This is slight overkill for many cases,
    but until we have identified which do not modify the data-structures it
    is wise to keep as we are.
