Ick.  Please replace buf[pagesize + 16] in the beginning of that
function by buf[256 + 16] (256 is the maximal page size of an AVR), as
a stop-gap measure.  pagesize is initially 0 when we enter the
function, so we allocate 16 bytes only.  Then we notice it's 0, and
invent an artifitial 128 bytes pagesize.  Obviously, now the buffer's
way too small for the data to fit.

I think the actual error is that the paged write function should not
be called at all, but I have to think a bit about that.

Please file a bug report, so we'll make sure this won't be forgotten.
