Gnucash 3.0 will not go beyond splash screen

[Bill Starrs]

Hello,

I upgraded to 3.0 yesterday on Archlinux.  I have been using MariaDB for
storage for a few years.

I have tried a few times to launch the new GnuCash.  It finds
Finance:Quote, prompts me for the database user and password, then just
hangs at the splash screen.

Launching from the terminal I get no messages or output of any kind,
waited about 2 hours before killing the process last time.

Any thoughts?

Thanks,

Bill Starrs
