[PATCH] logo: work around broken inkscape in Debian Trixie

[Sascha Hauer]

This works around a broken inkscape in Debian Trixie. With
Inkscape 1.4 (e7c3feb100, 2024-10-09). When executing multiple inkscape
instances in parallel it often fails with:

terminate called after throwing an instance of 'Gio::DBus::Error'

This is described in [1] and this patch utilizes a workaround from this
thread.
