This does work. Sadly it is not the arrow I want to have.
MWE:
\starttext
$A \xrightarrow{}{} B$
\stoptext
No problem here.
It seems to be a problem with the font I use.  Hans, do you have any idea why that does not work if I am using Minion Math? I am getting the following error:

attempt to get length of local 'charlist' (a nil value)
