export as postscript does not export anything

[Nabil Hathout]

Hello,

I was using lyx 1.0.3 (debian package) for some time. I have just tried to
export a lyx document in postscript.  It used to work on 1.0.0 but this
time it failed. I then moved to 1.0.4 but the exportation did not work
either. It does work in dvi. I then have to run dvips by hand.

Is it a bug, or do I have to set some parameters in my lyxrc ?

Thank you,
