You started a keyword but it seems to be an invalid one. The first character(s)
might give you a clue. You might want to quit unwanted lookahead with \relax.

it works fine.

Add \relax after the last skip value, i.e.

     \spaceskip = 1pt plus 1pt minus 1.5pt\relax

LMTX allows multiple plus and minus values for a skip value and the M in 
Matilda starts the scan for an additional minus value.

Wow, this sounds interesting. Is there an example of how to use multiple values?

Thanks for the fix! Steffen

I think the only examples are in mails from Hans. When you set multiple 
plus or minus values (as far as i remember) only the last setting is 
used and all previous ones are ignored.

Maybe in some article. Anyway, here is an example:

\starttext
     test \skip0=10pt plus 10pt minus 10pt plus 20pt

     test \skip0=10pt plus 10pt plus 20pt minus 10pt

     test \vrule width 10pt height 10pt depth 10pt depth 10pt height 10pt

  %  test \hbox to 10pt to 10pt {x}

\stoptext

compare pdftex and luametatex.

ok. but why does this run fine

\starttext

Test \spaceskip = 1.0pt plus 1pt minus 1.5pt Wolfgang

\stoptext


while this ends in an error message?


\starttext

Test \spaceskip = 1.0pt plus 1pt minus 1.5pt Matilda

\stoptext

because scanning is case insensitive so the m triggeres the keyword 
error ... keep in mind that by omitting a \relax you've always been 
lucky so far (probably no follow up texts that had plus or minus) .. 
luametatex just warns earlier
