Wayne Mery: sorry.

I have some results - as follows.

Log level | Any log output | Format of any log content | Logging clears up the filter problem
--------- | -------------- | ------------------------- | --------
1 | N | NA | N 
2 | N | NA | N 
3 | N | NA | Y 
4 | Y | hex | Y 
5 | Y | plain text | Y 


So: setting the log level between 1 and 3 produces no log, though a log level of 2 - and above - does solve the very problem we are trying to diagnose. The log produced at level 4: is hex; is some 1.4 MB (at present); seems to contain mostly zeros. I would attach that log but I do not know what it (in its non-zero parts) encodes.

I can (re-)enable logging at level 5 and see whether any of the resulting log seems useful, even though at that log level, the logging solves the problem.
