[GNC] Errors after restarting GnuCash 4.10 from terminal or bash script

[davidcousens49 at gmail.com]

I have just setup getting finance quotes for Gnucash for the first time for GC
4.10 on Linux Mint 20.3. I was setting up a shell script to shutdown GnuCash,
update the finance quotes and restart GnuCash after the quotes had been written
to the datafile. The finance quote seems to work ok but when I restarted GnuCash
from the script, the following appeared in the terminal after the script exited.

$ Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/gnucash/gnucash_core_c.py", line 14, in
swig_import_helper
    return importlib.import_module(mname)

During handling of the above exception, another exception occurred:

Found Finance::Quote version 1.51.

I get the same error with no additional info restarting GnuCash from the command
line with --debug. It seems to be more associated with the python bindings than
anything to do with getting online quotes. I do compile  with -D WITH_PYTHON+ON
when I build it. Haven't ever started GC from a script or terminal recently but
I presume this happens from the desktop launcher as well, just isn't visible.

Has anyone struck this before?
