"at_scale_size_prepared_cb: assertion 'width > 0 && height > 0' failed" on some document files
Fedora 38, nautilus-44.0-1.fc38.x86_64, libgsf-1.14.50-1.fc38.x86_64.
When gsf-office-thumbnailer generates thumbnails, it returns this failed assertion on some of my document (ppt) files although all the files seem to be correct:
(gsf-office-thumbnailer:14711): GdkPixbuf-CRITICAL **: 12:27:28.933: at_scale_size_prepared_cb: assertion 'width > 0 && height > 0' failed
(gsf-office-thumbnailer:14711): GLib-GObject-CRITICAL **: 12:27:28.933: g_object_unref: assertion 'G_IS_OBJECT (object)' failed
Also, the generated thumbnail looks broken:
(But that may be a different problem since it happens only in some cases.)
Here is one of the files as an example.
