[HELP] Positioning Minimap > Blizz Bar Error

[Zenjaa]

Hello.
Maybe someone can help me out with a somewhat weird issue.

I'm using my own Minimap addon which works completely fine except for a positioning issue.

This is the part of the addon which positions the minimap, which works fine.

local cfg = {
  scale = 1,
  point = { "TOPRIGHT", UIParent, "TOPRIGHT", -25, -2},
}

BUT...
as soon as I try to position the map in the bottomright corner the following error occurs:

74x FrameXML\MultiActionBars.lua:85: MultiBarRight:SetScale(): Scale must be > 0
[C]: in function `SetScale'
FrameXML\MultiActionBars.lua:85: in function `MultiActionBar_Update'
FrameXML\InterfaceOptionsPanels.lua:1184: in function `InterfaceOptions_UpdateMultiActionBars'
[string "*:OnLoad"]:4: in function `setFunc'
FrameXML\InterfaceOptionsPanels.lua:1154: in function <FrameXML\InterfaceOptionsPanels.lua:1147>

Locals:
(*temporary) = MultiBarRight {
 0 = <userdata>
 slideOut = <unnamed> {
 }
}
(*temporary) = -0.22465210264293

Apparently the blizz code is scaling the actionbars (right bars/multibars 4/5) if I move the minimap somewhere near the area where they are!?

Can anybody tell me why this is happening and what steps to take lua-wise to get rid of this behavior?
Any help would be greatly appreciated.
