I reported this originally as part of a ticket to Grid:
http://www.wowace.com/addons/grid/ti...resurrect-lua/
It was marked fixed for Grid, but the bug is still present. I thought it would be a good idea to report it here, as the bug is in this library.
Grid-r1536\Libs\LibResInfo-1.0\LibResInfo-1.0-4.lua:185: attempt to compare nil with number

The lua error can be removed with the following, although there is probably a better fix.
$ diff LibResInfo-1.0.lua.old LibResInfo-1.0.lua

> if endTime and (not firstEnd or endTime < firstEnd) then
I do not know why sometimes "local endTime = castEnd[casterGUID]" is nil.
