wmpomme has a direct Depends on the dbus package, which prevents it
from being used in conjunction with the non-default dbus-broker package
as a system bus. Similarly, pommed has a Recommends on dbus.

For details of how to replace this dependency, please see:
https://salsa.debian.org/utopia-team/dbus/-/blob/debian/unstable/debian/replacing-dbus-dependency.txt?ref_type=heads

Given the purpose of this package, I'm guessing the intention of this
dependency is "this package needs a working system bus", similar to
polkitd or network-manager. If that's the case, please replace each
Depends/Recommends on dbus with:

default-dbus-system-bus | dbus-system-bus
