[texhax] fatal errors with footnote italics for critical edition

For a critical edition (Mac OS, ledmac, TeXShop, all latest versions) with double 
footnotes, my B footnotes are vulnerable to random "fatal errors" when text is 
italicized.  These fatal errors tend to happen when B footnotes follow A 
footnotes, or when B footnotes reach some kind of length or formatting limit.  
The error disappears when the italicization is removed.

Error first, preamble next.  Both \textit and my macro \I generate the same 
error.    Other macros: \edt = \edtext  \A = Afootnote  \B = Bfootnote

\edt{ananas}{\A{\I{Ananasses} F; Anana's H}}{\B{pineapples (Fr. \I{ananas})}}, 
\edt{which to my taste}{\A{\sout{I} to H; which, to my taste, F}}

\setlength\parindent{0.25 in}

Some workarounds seem to help - pasting in B footnotes first, nesting B 
footnotes within the lemma, adding \newcommands that embed the italics in 
the text.  But no workaround works around consistently, or helps me 
understand why italics create fatal errors at all.

Grateful in advance for any help, and for patience with a learning user in
