ImageMagick with RSVG conversion errors

[Insalien]

Problem description
Issue related to imagemagick or precisely with rsvg-convert

$ convert test.svg test.png
bionic/libc/upstream-netbsd/lib/libc/stdlib/bsearch.c:70: bsearch: assertion "key != NULL" failed
Aborted
$ rsvg-convert /sdcard/test.svg -o test.png
bionic/libc/upstream-netbsd/lib/libc/stdlib/bsearch.c:70: bsearch: assertion "key != NULL" failed
Aborted

Steps to reproduce
I can't upload svg file but the testing content is pretty small

<svg xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:cc="http://creativecommons.org/ns#" xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:svg="http://www.w3.org/2000/svg" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:sodipodi="http://sodipodi.sourceforge.net/DTD/sodipodi-0.dtd" xmlns:inkscape="http://www.inkscape.org/namespaces/inkscape" width="640" height="1000" pagecolor="#ffffff" viewBox="0 0 744.09449 1052.3622" id="svg2" version="1.1">
  <g id="group_data">
    <text>Test</text>
  </g>
</svg>

Expected behavior
Conversion is done

I'm unsure that issue is related to imagemagick with librsvg.

The line

bionic/libc/upstream-netbsd/lib/libc/stdlib/bsearch.c:70: bsearch: assertion "key != NULL" failed

clearly states that issue is in your ROMs libc (maybe for all libc's at Android v6.0 and lower).

Googling shows that issue may occur not only with imagemagick like in Termux case:

@xeffyr hey thank you for your quick response. I have several devices in both arm and aarch64 arch and only this one in arm having this issue. Let's say there's some incompatibility between termux libsrvg(arm) and the libC in our ROM. I'll try to dig into it further.

There is still one tiny problem that I didn't mention earlier because it's not related to the original question but after installing imagemagick and depending on the svg, the conversion might not work because of

(process:32277): GdkPixbuf-WARNING **: 19:01:39.235: Cannot open pixbuf loader module file '/data/data/com.termux/files/usr/lib/gdk-pixbuf-2.0/2.10.0/loaders.cache': No such file or directory

This likely means that your installation is broken.
Try running the command
  gdk-pixbuf-query-loaders > /data/data/com.termux/files/usr/lib/gdk-pixbuf-2.0/2.10.0/loaders.cache
to make things work again for the time being.

Everything is fine after I followed the suggestion.
You might consiger adding a gdk-pixbuf.postinst in this case.

Thanks @xeffyr, the fix that you did on pango package is working for me. The ticket can be closed unless @tondy67 want to add anything.

Hi, my X11 (openbox,geany,pcmanfm) is still broken.
I installed Termux from scratch - no luck
I installed all libandroid-*-static - no luck
I installed fluxbox, it works, at least I can start aterm
I use nano && mc to continue my work but it's not the same as geany && pcmanfm
Maybe is x32 related, my tablet is old...
