Darren didn't include the complete traceback, but it seems that dviread
does get used by TexManager.get_text_width_height_descent unless the
text.latex.preview parameter is set. So if preview.sty is available,
setting the parameter might help with that particular problem.

I thought subprocess.el handled EINTR, but apparently not:

http://bugs.python.org/issue1068268

I guess the reason why some people run into this and others don't is
that (some) GUI toolkits make use of signals, and the probability of
receiving a signal while reading from the subprocess pipe depends on
various system-specific details.
