I have seen this, too---manifesting as an taffybar not starting---though
I was doing some more investigation before I enquired.

I was able to roll back to a version that worked, and the clearly
distinguishing feature was that there was only one listing in
DBUS_SESSION_BUS_ADDRESS; and indeed, if I set the environment variable
when starting taffybar, it works fine.

  $ DBUS_SESSION_BUS_ADDRESS=unix:abstract=/tmp/dbus-jp8hFEY1dV,guid=c6e01dc144bda2ae4ca47c84580747a5 taffybar 

Works just fine.

I guess the question I'm left with is whether the error is in the nix
configuration providing us with two entries in the variable, or in the
haskell dbus package in not handling it properly?
