Hello,

here is a minimal sample which doesn't compile:

----
\starttext
   \startitemize
     \item
       A\footnote{%
         B
         \startitemize
           \item C
         \stopitemize
       }\crlf
       D

     \item E % <<<< This sample compiles when this line is commented (?!)
   \stopitemize
\stoptext
----

The error message is:

"
...
...eta/tex/texmf-context/tex/context/base/mkiv/strc-num.lua:465: attempt 
to index a nil value (local 'd')

  2       \startitemize
  3         \item
  4           A\footnote{%
  5             B
  6             \startitemize
  7               \item C
  8             \stopitemize
  9           }\crlf
10           D
11
12 >>      \item E % <<<< This sample compiles when this line is 
commented
13       \stopitemize
14     \stoptext
15
"

When the "\item E" is commented, the sample compiles successfully.

Any idea what's going wrong?

Best regards,
