mythfilldatabase segfaulting

Anyone else having issues with mythfilldatabase segfaulting on Ubuntu
20.04?

I noticed this morning that my boot drive was full due to /tmp having TONS
of mythXXXX temp files (xml outputs from mythfilldatabase). When I looked
into it, I saw that mythfilldatase was segfaulting (see log below).

The only thing I've changed recently was to change the mythbackend
password. Possibly I missed a config file somewhere?

Are you able to get a backtrace so we can narrow this down?

I have one now - but it's a large file (9.3mb). Is there a suggested place
to upload it to (possibly github with a ticket)?

Here's a truncated version
