Comment 1 Pietro F. Fontana 2020-04-19 09:34:54 UTC 
If I try to start it again from command line with 'balooctl enable':

Enabling and starting the File Indexer
replace called with invalid arguments, docId: 1103806595128 url: "/home/cubanpit/"
mdb.c:2127: Assertion 'rc == 0' failed in mdb_page_dirty()
KCrash: Attempting to start /usr/bin/baloo_file from kdeinit
sock_file=/run/user/1000/kdeinit5__1
KCrash: crashing... crashRecursionCounter = 2
KCrash: Application Name = baloo_file path = /usr/bin pid = 5313
KCrash: Arguments: /usr/bin/baloo_file 
KCrash: Attempting to start /usr/lib/drkonqi from kdeinit
sock_file=/run/user/1000/kdeinit5__1

I purged the index database and restarted Baloo, now it works again.
This means that I will not be able to reproduce the issue anymore, sorry.
