Invalid access to free'd memory after DeleteLinesMatching

Hi,

cfengine-2.2.8 segfaults on rules like

----
control:
        actionsequence = ( editfiles )

editfiles:
        { /tmp/foo
                DeleteLinesMatching "foo"
                LocateLineMatching "foo"
        }
----

when '/tmp/foo' contains 'foo' string.  Analyzing this with 'valgrind'
gives

==4784== Invalid read of size 8
==4784==    at 0x423348: LocateItemMatchingRegExp (item-ext.c:394)
==4784==    by 0x4357D9: DoEditFile (edittools.c:577)

--> LocateItemMatchingRegExp() is called with a CURRENTLINEPTR which
points to memory free'd by DeleteItemGeneral
