Bug description

This appeared during a raid in UBRS when the raid group icons updated, hard to reproduce because it's in a raid:

1x [ADDON_ACTION_BLOCKED] AddOn 'Questie' tried to call the protected function 'CompactRaidFrame11:SetAttribute()'.
[string "@!BugGrabber\BugGrabber.lua"]:519: in function <!BugGrabber\BugGrabber.lua:519>
[string "=[C]"]: in function SetAttribute' [string "@FrameXML\CompactUnitFrame.lua"]:163: in function CompactUnitFrame_SetUnit'
[string "@Blizzard_CompactRaidFrames\Blizzard_CompactRaidFrameContainer.lua"]:318: in function CompactRaidFrameContainer_AddUnitFrame' [string "@Blizzard_CompactRaidFrames\Blizzard_CompactRaidFrameContainer.lua"]:254: in function CompactRaidFrameContainer_AddPlayers'
[string "@Blizzard_CompactRaidFrames\Blizzard_CompactRaidFrameContainer.lua"]:176: in function CompactRaidFrameContainer_LayoutFrames' [string "@Blizzard_CompactRaidFrames\Blizzard_CompactRaidFrameContainer.lua"]:130: in function CompactRaidFrameContainer_TryUpdate'
[string "@Blizzard_CompactRaidFrames\Blizzard_CompactRaidFrameContainer.lua"]:57: in function `CompactRaidFrameContainer_OnEvent'
[string ":OnEvent"]:1: in function <[string ":OnEvent"]:1>

Questie version

Ver. 6.3.12

Merging this with #2936

We are aware of this taint issue but haven't found a way to fix it without losing functionality.

This seems to continue on with 6.3.15. I had this together with poisoner and missingtradeskilllist. First the error fell on poisoner. Then I removed poisoner and it fell on missingtradeskillist. Then I removed missingtradeskilllist and the error fell on Questie. Then I removed questie and it never appeared again.

It appears to happen when there's a change in status of a group member when in a dungeon group (if they level, if they leave, etc.)

This was the error in 6.3.15:

1x [ADDON_ACTION_BLOCKED] AddOn 'Questie' tried to call the protected function 'CompactRaidFrame2:Show()'.
[string "@!BugGrabber\BugGrabber.lua"]:519: in function <!BugGrabber\BugGrabber.lua:519>
[string "=[C]"]: in function Show' [string "@FrameXML\CompactUnitFrame.lua"]:359: in function CompactUnitFrame_UpdateVisible'
[string "@FrameXML\CompactUnitFrame.lua"]:292: in function `CompactUnitFrame_UpdateAll'
[string "@FrameXML\CompactUnitFrame.lua"]:125: in function <FrameXML\CompactUnitFrame.lua:53>

This happened when we were in Mana Tombs.

Hope this further information is useful.
