Bug in startitemize

Bug in startitemize

[Otared Kavian]

Hi Hans,

It seems that with the new beta (ConTeXt  ver: 2016.03.04 10:39 MKIV beta  fmt: 2016.3.7), there is a bug with random itemization.
I cannot tell exactly when this feature has been broken.
The problem is that for instance in the following example, sometimes the item C is repeated three times, sometimes A is repeated twice, etc.

\starttext

\startitemize[n,random]
\startitem A \stopitem
\startitem B \stopitem
\startitem C \stopitem
\stopitemize

\stoptext

Best regards: OK

Thanks Wolfgang,

Your patch does indeed solve the problem, after rebuilding with

	context --make —all

Best regards: OK
