I could reproduce the problem with this simple example:

\usemodule[simplefonts]
\setsansfont[nimbus]

\starttext
An equation $e^{\pi i}+1=0$, or as a
\stoptext

Any idea why it doesn't work ?

What happens when you remove the \setsansfont line (the Nimbis isn’t even used in the example)?

When I remove the \setsansfont it works perfectly...

When I but back the \setsansfont I have the following error:

1     \usemodule[simplefonts]
2     \setsansfont[nimbus]
3
4     \starttext

6     \stoptext

l.5 An equation $e^{\pi i}+1=0$
                               , or as a
?

Is there also a error message?

Yes :
