Dear Maintainer,
I tried to investigate a little further and think
I have found some details.
When starting inkscape from a terminal and opening the
given PDF shows a "double free" message.
A valgrind run [2] shows the causing lines at a first glance.
On a second look [3] it might be related to
having the PDFDoc object constructed by libpoppler.so.123.
But the deconstructor is called from libpoppler.so.118.
These two versions of lippoppler in the same process seem
to be caused by the old version 1.1.2-3+b1 of inkscape still in testing
and the new version 1.2.1+ds-1 not transitioning
from unstable to testing [4] [6].
Unfortunately libpoppler-glib8 is already in a version in testing
that is pulling the newer libpoppler.so.123 into the process. [5]
As a workaround it might work to install just the inkscape package
from unstable into a testing system. The PDF import worked at least
for me in my test VM without this issue.
Kind regards,
Bernhard
