I have a fix in user-fixes.py that has run smoothly over thousands of pages with a file containing the pages to be changed.
So this fix is not the problem per se.
But now I want to run this fix with an XML dump as a page generator.
But this attempt is immediately terminated with the following error message:
```
bot@udo-t:~/pywikibot-core$ python3 pwb.py replace -lang:de -ns:0 -xml:./dump/dewiktionary-latest-pages-articles.xml -fix:nbsp

I have three other fixes (with replace.py) that have been running automatically (via shell schript and cron) for a very long time whenever there is a new XML dump.
On 21 March, these still worked. But shortly after 01 April, when there is another new xml dump, these 3 fixes stopped working. If I now enter each of these in the command line, I also get the above error message for these 3 fixes.
By the way, I saw that replace.py and also pagegenerators.py were last changed on 26 March.
