Many thanks! Although this doesn't quite solve the bug yet, now I know  
where to look ...

Test case:

---
\starttext

\math{\primes P},
\math{\naturalnumbers N},
\math{\integers Z},
\math{\rationals Q},
\math{\reals R},
\math{\complexes C}

\stoptext
---

Proposed patch:

diff math-def.mkiv.orig math-def.mkiv
100,105c100,105
< \definemathcommand [integers]      {\mathblackboard{Z}}
< \definemathcommand [reals]         {\mathblackboard{R}}
< \definemathcommand [rationals]     {\mathblackboard{Q}}
< \definemathcommand [naturalnumbers]{\mathblackboard{N}}
< \definemathcommand [complexes]     {\mathblackboard{C}}
< \definemathcommand [primes]        {\mathblackboard{P}}
---
 > \definemathcommand [integers]      {{\mathblackboard Z}}
 > \definemathcommand [reals]         {{\mathblackboard R}}
 > \definemathcommand [rationals]     {{\mathblackboard Q}}
 > \definemathcommand [naturalnumbers]{{\mathblackboard N}}
 > \definemathcommand [complexes]     {{\mathblackboard C}}
 > \definemathcommand [primes]        {{\mathblackboard P}}

Hans, Aditya, does this make sense?
