Errors when using an Ace3 addon?

[10leej]

So since working on my DBM skin I've noticed that I keep getting this error in combat

4x [ADDON_ACTION_BLOCKED] AddOn "BobUI" tried to call the protected function "MultiBarBottomLeftButton4:Show()".
!BugGrabber-r198-release\BugGrabber.lua:552: in function <!BugGrabber\BugGrabber.lua:552>
<in C code>
FrameXML\ActionButton.lua:268: in function <FrameXML\ActionButton.lua:253>
<in C code>
FrameXML\ActionButton.lua:523: in function "ActionButton_OnEvent"
FrameXML\ActionButton.lua:124: in function <FrameXML\ActionButton.lua:117>

Locals:
nil

My source code

I imagine it had something to do with my hacked version of a fade code for my actionbars, but I don't know why I only get this error when I'm using an addon with an Ace3 library I've noticed this with Aurora and TellMeWhen. This only seems to be happening lately, but I admit I haven't played much until this recent patch.
