Comment 14 for bug 1651815

Opening calligraphy-f07.svg generates the following warning (repeated about 30 times):

** (inkscape:30309): CRITICAL **: SPObject* SPDocument::getObjectById(const gchar*) const: assertion 'id != NULL' failed

No warning when opening the same file with 0.91, and using 0.91 to generate the calligraphy files with the inkscape-docs automated process works as expected.
So at least we have a workaround. Now I'm going to investigate if the warning can be fixed in the faulty file or if the bug is in Inkscape itself.
