[GNC] Setting "Retain log files" to "never" doesn't seem to work

[Chris Green]

I have "Retain log/backup files" set to "Never" in my Gnucash
preferences but I'm still getting a log file created every time I run
Gnucash.

I'm running GnuCash 3.10, Build ID: 3.10+(2020-04-11) on Xubuntu Linux.
I'm using sqlite rather than XML, might this be having an effect?

Is this a known bug/issue or am I doing something wrong?
