Inkscape doesn't render formulas with the Latex extension

[Till Sachau]

Affects inkscape 0.92.3-1 on Bionic Beaver development version

On hitting 'Extensions -> Render -> Latex' the usual interface to insert a latex formula appears, but on hitting 'Apply' stops with the following error:

PostScript/PDF Interpreter finished. Return status 65280 executed command : /usr/bin/gs -I/home/till/.fonts -q -dDELAYBIND -dWRITESYSTEMDICT -dNODISPLAY -dNOEPS "/tmp/psinVP0LD1"

The interpreter seems to have failed, cannot proceed !

Full output (including a ghostscript warning) given below:

 *** WARNING - the DELAYBIND command has been deprecated, and will be

               removed in the next version. For now you can restore

               the behaviour by using -dREALLYDEALYBIND but if you

               require continued use of this command you should contact

               the Ghostscript developers. Commercial customers of

               Artifex should email their support contact, free users

               are encouraged to talk to us on the #ghostscript IRC

               channel on irc.freenode.net.

Status changed to 'Confirmed' because the bug affects multiple users.

I'm on Debian testing and installed the update from unstable:

Package pstoedit:
p A 3.70-5+b1 testing
i A 3.71-1 unstable

However it does not fix the issue for me, with the same error. Anyone else seeing this?

Note the command mentioned in the debian thread:

pstoedit -f plot-svg /tmp/drawing.pdf /tmp/drawing.svg

Also still crashes.

As a temporary workaround, downgrading libgs9-common, libgs9 and ghostscript packages to version 9.21 from the Artful repositories helps.

It works on bionic.
