That doesn't look like the version of the kernel library auto object
which comes with 1.2.105.

But you've found a bug in the kernel library.  This can be fixed by
adding

    ::call_trace()[1][TRACE_FIRSTARG][1] = nil;

or, for the most recent kernel library,

    TLSVAR2 = nil;

before the calls to ::editor() (2 lines before where the error happens).
I'll include an official fix in the next DGD patch (hopefully this weekend,
I have some DGD/MP bugs to fix first).
