actually it's the \type (combined with colors)
\dontleavehmode \type {xx}
works ok
probably some pdfliteral is playing havoc here so that the width analyer
cannot function well (a limitation of tex is that there's only a small
set subset of \un* and \last* node operations); if you see messages like
this
!!forced exit from shapebox 9!!
that is indeed the case. hoewver, in mkiv i use different trickery so
there we don't have this problem (we also use a different color
mechanism so that helps too)
it's not so much a bug in mkii as well as a side effect/limitation
okay, we could add \dontleavehmode to \type but i'm not sure if that
will not break other things; also, bTABLE is kind of tricky because it
needs to be clever with regards to text and non text and such
