When I have the "Zone Map" showing (press SHIFT-M) and log in with just Shadowed Unit Frames I get the Lua error below.

When I have Shadowed Unit Frames disabled this goes away. I don't know why it's affecting Blizzard_BattlefieldMap but when I don't have the Zone Map showing then this error does not occur.

I have the latest version of Shadowed Unit Frames and I deleted my WTF and cache folders before running this test.

Please let me know if you need any more info :) Thanks.

EDIT: It's the "Hide Party Frames" option causing the problem. If it's enabled and I have the Zone Map showing I get this bug on `/reload`

Looks like when you unregister all events from each party frame then the bug occurs. As though something needs to be triggered but it can't trigger.
