! LuaTeX error ...t-04/tex/texmf-context/tex/context/base/grph-inc.lua:221: bad argument #1 to 'match' (string expected, got nil)
stack traceback:
[C]: in function 'match'
...t-04/tex/texmf-context/tex/context/base/grph-inc.lua:221: in function 'guess'
...t-04/tex/texmf-context/tex/context/base/grph-inc.lua:1145: in function <...t-04/tex/texmf-context/tex/context/base/grph-inc.lua:1143>

...t-04/tex/texmf-context/tex/context/base/grph-inc.lua:862: in function 'identify'
<main ctx instance>:1: in main chunk.
The version used is:
ConTeXt ver: 2012.10.06 15:31 MKIV fmt: 2012.10.13 int: english/english
Is there a quick fix, or I get stuck at a bad moment.
Thanks in advance.

function figures.guess(filename)
local f = io.open(filename,'rb')
if f then
local str = f:read(100)
f:close()
if str then
for i=1,#magics do
local pattern = magics[i]
if pattern.pattern:match(str) then
local format = pattern.format
if trace_figures then
report_inclusion("file %q has format
%s",filename,format)
end
return format
end
end
end
end
end
One might wonder why str is nil.
