[tex-live] xdvi crashes

[Karl Berry]

FWIW ... if it's about font generation, you could remove any generated
fonts, e.g., rm -rf ~/.texlive2014/texmf-var/fonts, and then run xdvi
like env MKTEXPK=0 xdvi foo.xdvi, and it shouldn't try to remake any
pk's.  (I'm guessing MKTEXMF and MKTEXTFM wouldn't be relevant.)  At
least then it would be a reproducible situation.

Another approach that comes to mind is to set TEXMFVAR and TEXMFSYSVAR
to different directories for each run.

Just a thought.
