Whole system (ubuntu) freezes when printing

[Stefan Wagner]

Ubuntu 15.10, Inkscape 0.91 r13725

I made a page with text, rotated, a semitransparent white rect above, and other text on top. It's supposed to be decoration of the backside of business cards plus the signature of my GPG.

When I try to print, no matter whether I print to my HP4P LaserJet or to a PDF in standard settings, the whole system freezes for minutes, no mouse moves accepted, no keyboard stroke, even the clock freezes after 1-2 seconds.

Hard reboot is the only option.

Exporting as PNG works.

A maybe related error showed up when I started from the command line. Starting Inkscape with:

> LC_ALL=C inkscape visitenkarten-2016-rs-3.svg

to produce an english error message curiously doen't produce an error message at all. So I translate the german message freely, after posting the original:

> (inkscape:3560): Gtk-WARNING **: Failed to set text from markup due to error parsing markup: Fehler in Zeile 1: Entität endete nicht mit einem Semikolon; wahrscheinlich haben Sie ein »&«-Zeichen verwendet, ohne eine Entität beginnen zu wollen - umschreiben Sie das »&« als »&«

The same message appears 2 times. Here my translation:

> (inkscape:3560): Gtk-WARNING **: Failed to set text from markup due to error parsing markup: Error in line 1: Entity did not end in a semicolon; probably you used a »&«-symbol, without wanting to start an entity - rewrite the »&« as »&«

Well, I have plenty of &-Symbols but all as parts of an entity, ">" which shall add to an arrow as such: "=>". (Haha, side note: I'm curious, whether the markup of this site will handle my message well.)

Here is a pattern of the SVG source:

 grep "&" visitenkarten-2016-rs-3.svg
           id="tspan8225"> case aa :: bb :: Nil =&gt; </tspan><tspan
           id="tspan8227"> aa.map (a =&gt; bb.map (b =&gt; List (a, b))).flatten </tspan><tspan
           id="tspan8229"> case aa :: bb :: cc =&gt; </tspan><tspan
           id="tspan8231"> xproduct (bb :: cc).map (li =&gt; aa.map (a =&gt; a :: li)).flatten</tspan><tspan
           id="tspan8233"> case _ =&gt; xx</tspan><tspan

Here is the test for an unclosed &-entity:

grep "&" visitenkarten-2016-rs-3.svg | grep "&gt[^;]"

(No output).

Please note, that the GPG-signature in the file is not secret and needn't be anonymized.

I'm not sure whether it is a security vulnerability, but I think so, since it halts the whole system. Please note further, that the suspect, the ampersant might be the source of the problem, is just a wild guess.

Closing because not reproduced with Inkscape 1.0 alpha and with Ubuntu 18.04.
