In sellframe as well as some other places.

refer to shefki's post here. http://us.battle.net/wow/en/forum/topic/6413263287

auctionlite will break glyph UI because of bad code on blizzards part. Blizzard leaking _ as a global, but when mod authors call _ as a global instead of a local function, we taint the glyph UI.

These leaks need fixing in auctionlite to avoid problems.

such as this

  local name, color, enchant, jewel1, jewel2, jewel3, jewel4;
  local showPlus;

  if SellLink ~= nil then
    name, color, _, _, enchant, jewel1, jewel2, jewel3, jewel4 =
      self:SplitLink(SellLink);

in sell frame.

without local, you are simply calling blizzards leaked _ global and tainting glyph UI

need to use a local variable, or use something else here

something like

  local name, color, arg3, arg4, enchant, jewel1, jewel2, jewel3, jewel4;
  local showPlus;

  if SellLink ~= nil then
    name, color, arg3, arg4, enchant, jewel1, jewel2, jewel3, jewel4 =
      self:SplitLink(SellLink);

would avoid the problem in this example.

note, that example and file are not the only place with problem, look in externals too, and possibly other files, i didn't do a super search just skim.

This is the taint that I get from the taint log.

lol, i laughed at your solution. Simple bug effective. :)
