test fails

When packaging SLAXML for OpenSUSE, I get this error while running the testsuite:

Thank you for the report. This is a known issue, documented in the top bullet here:

https://github.com/Phrogz/SLAXML#known-limitations--todo

It is a goal of the library to be a proper validating parser, and so this test exists that is currently failing.

Sorry for bothering you, but I am lost, what’s wrong with this super simple script:

#!/usr/bin/lua
local SLAXML = require 'slaxml'

local myxml = io.open('CzeCEP.xml'):read('*all')

-- Czech version
local counter = { ["‚"] = 0, ["„"] = 0}
local counter_keys = ""
for k in pairs(counter) do
    counter_keys = counter_keys .. k
end

local qparis = { ["‚"] = "‘", ["‘"] = "‚", ["„"] = "“", ["“"] = "„" }

parser = SLAXML:parser{
  text = function(text,cdata)
            for ch in text:gmatch("[‚‘„“]") do
                if counter_keys:find(ch, 1, true) then
                    counter[ch] = counter[ch] + 1
                else
                    counter[qpairs[ch]] = counter[qpairs[ch]] - 1
                    if counter[qpairs[ch]] < 0 then
                        print("This is wrong: " .. text)
                        os.exit(1)
                    end
                end
            end
         end
}

-- Ignore whitespace-only text nodes and strip leading/trailing whitespace from text
-- (does not strip leading/trailing whitespace from CDATA)
parser:parse(myxml,{stripWhitespace=true})

When run, it fails like this:

xml-unpaired@stitny (master)$ lua dumptext.lua 
lua: dumptext.lua:19: attempt to perform arithmetic on a nil value (field '?')
stack traceback:
        dumptext.lua:19: in field 'text'

        dumptext.lua:33: in main chunk
        [C]: in ?

Any idea, what’s going on, please?
