Comment 4 for bug 1465163

Setting bug status to 'Triaged' for now - the problem with latest pstoedit 3.70 might hit users on other distros too.

To be investigated: how could (or even: should) the user be warned about a partially broken installation of pstoedit?

1) The current extension system checks for the presence of required (runtime) dependencies (e.g. pstoedit in $PATH) - it does not provide means to actually test whether the dependent helper tool is correctly installed. I somewhat doubt these checks could (or should) be expanded (it would require to work cross-platform).

2) Changing which messages (default: stderr of spawned processes) are returned via eqtexsvg.py to Inkscape probably should be coordinated with other related reports:
* Bug #1402731 “LaTeX formula extension improvements”
(proposes to silence error messages from pstoedit completely; comment 6)
and
* Bug #1408535 “latex render works but gives error message”
* Bug #1210287 “LaTeX renderer shows an error message (but does re...”
Bug #1210287 seems to be obsolete with pstoedit 3.70 though (AFAICT there's no more unwanted console output when outlining text in PostScript files).

3) Possibly eqtexsvg.py could run its own check whether the format 'plot-svg' is supported by pstoedit found in $PATH and warn the user in case SVG support is missing (instead of failing later on).
