Version 19.19

Get this a lot though I can't say what specifically causes it. Note that I was getting this before the 10.1.17 patch today.

31x [ADDON_ACTION_BLOCKED] AddOn 'BagSync' tried to call the protected function 'Frame:SetPassThroughButtons()'.

This error is not caused by BagSync. However, it's being blamed for another addons bug due to how Blizzards cascading error trapping works. Since BagSync starting with the letter "B" is higher than most other addons alphabetically. If you get it again then let me know, but I suspect it was another addon.

I want to point out that addon that is triggering it is "SilverDragon_Overlay" btw, if you look at the error, that was the addon that triggered it before BagSync was blamed.
