If an image file has metadata using non ASCII characters (e.g. accented letters) that are not UTF-8 encoded than Photini may crash when reading the metadata. The crash typically says something like "Error in `python3': munmap_chunk(): invalid pointer:" and prints a long backtrace.
As far as I can tell, this only happens when using Python3 and when using PyGobject rather than pgi. The quick fix is to install pgi: sudo pip3 install pgi.
