[XeTeX] qtree errors

[Joshua and Amy]

When I typeset a document with QTree trees (using XeLaTeX in TeXShop) I get
hundreds of errors. But the output PDF looks just fine.

The bulk of the errors are something like this:

 ** WARNING ** Unknown token "save"
** WARNING ** Interpreting PS code failed!!! Output might be broken!!!
** WARNING ** Interpreting special command ps: (ps:) failed.
** WARNING ** >> at page="1" position="(192.561, 551.643)" (in PDF)
** WARNING ** >> xxx "ps: save /setgray { pop } def"
** WARNING ** >> Reading special command stopped around >>/setgray { pop }
def<<
** WARNING ** Unknown token "restore"
** WARNING ** Interpreting PS code failed!!! Output might be broken!!!
** WARNING ** Interpreting special command ps: (ps:) failed.
** WARNING ** >> at page="1" position="(192.561, 551.643)" (in PDF)
** WARNING ** >> xxx "ps: restore"
** WARNING ** Unknown token "save"

Attached you'll find the tex file and the log.

I found a 2007 post by Jonathan K that suggested the call
\usepackage[dvipdfm]{pict2e} for people using QTree. It takes care of the
problems. But are there any drawbacks of using this to fix the problem? Is
there a better solution?

Thanks!
