[NTG-context] "Too many }'s" in latest beta

Hello, When running `context test.cld' on this file: --8<---------------cut here---------------start------------->8--- context.environment{"my-env"} -- it does not matter, if this file exists or not context.starttext() context.startalignment{"middle"} context"Amount: 123" context.stopalignment() context.stoptext() --8<---------------cut here---------------end--------------->8--- I get the following error: system > tex > error on line 11 in file test.run: Too many }'s ... [1] How could I solve this problem please? core-env.mkiv is patched on line 226 as suggested by Wolfgang. TIA for any help, -- Peter [1]: test.run has only one line... ;-)
