While (on the other machine) Tk804 seems happy-ish, on
this laptop I am attempting to catch up on my mail
using bleadperl + UTF8-aware tkmail but non Unicode Tk800.
It seems to be discovering a snag.
When I try and read Autrijus Tang's latest posting to
perl-unicode with that I get a malloc related segfault:
Program received signal SIGSEGV, Segmentation fault.

Note that in _this_ case use of tkmail is using fallbacks - so I suspect
(no proof yet) that "new" fallback insert can buffer-overrun, and so destroy
the malloc data structures.
