Yes and no. No. Apache runs as user www-data, who doesn't have many
permissions. Yes www-data has write access to the directory and files
where it is exporting.
See my later e-mail, where the bug turns out to be subst() getting stuck
in a loop (probably because it is getting called with a null string.)
The workaround is to set the $HOME environment variable, though the code
should probably catch this somewhere. If it is a fundamental
assumption that $HOME is set, maybe lyx should die really early.
Otherwise, something like checking for $HOME before using it to call
subst(), or maybe having subst() check its parameters before getting
stuck in a while loop...
