Grsync Starts Very Slowly In Ubuntu 20.04

I just did a clean install of Ubuntu 20.04 on two machines, and in both cases, Grsync takes a very long time to start. I tried it with both a fresh grsync.ini file and my existing one, and it made no difference.

When I started Grsync from Terminal, the only error was that canberra-gtk-module was missing. Installing it and rebooting did not improve Grsync's loading speed.

To give you an idea of how slow Grysnc's startup really is, here's the start time of LibreOffice Writer as shown by the time command:

time libreoffice --writer
real 0m2.771s
user 0m1.130s
sys 0m0.108s

and here's the start time of Grsync:

time grsync
real 0m37.736s
user 0m0.210s
sys 0m0.016s

So LibreOffice starts in only 2.771 seconds, and it takes Grsync 37.736 seconds to start!

The fix/workaround, identified in this post (https://ubuntuforums.org/showthread.php?t=2441572&p=13950711#post13950711) by @rbmorse, is to install appmenu-gtk2-module and reboot. Following that, time shows the following for Grsync:

time grsync
real 0m8.669s
user 0m0.110s
sys 0m0.022s

I guess libcanberra-gtk-module and appmenu-gtk2-module just need to be added as dependencies for Grsync in Ubuntu 20.04?
