Parsing a pywikibot generator over the pages referring [[:c:Template:Monument istoric]] started crashing when parsing the file https://commons.wikimedia.org/wiki/File:CATEDRALA_EVANGHELICA_SIBIU.jpg
The contents of the file_revision variable as parsed by PWB is: {'descriptionurl': 'https://commons.wikimedia.org/wiki/File:CATEDRALA_EVANGHELICA_SIBIU.jpg', 'filemissing': '', 'descriptionshorturl': 'https://commons.wikimedia.org/w/index.php?curid=16462988'}
The backtrace I get is:

AttributeError: 'FileInfo' object has no attribute 'timestamp'
CRITICAL: Exiting due to uncaught exception <class 'AttributeError'>This is caused by the weird first version of the file which has no preview and has likely been uncovered by the fix in T233392. A fix in PWB should probably include ignoring revisions containing the 'filemissing' flag (which is undocumented - see T109125) but seems to indicate a problem with the image.
However, I believe the MediaWiki team should also take a look at why that version is missing an image - @Aklapper , could you please add the relevant people in CC?
