Hi, list!
When I try to convert a PDF generated by ConTeXt LMTX to PNG using
ImageMagick's convert the following happens:
**** Error: stream Length incorrect.
Output may be incorrect.

I'd blame ImageMagick, except for the fact that 1) other converters fail
too and 2) it doesn't happen with ConTeXt MkIV (PDF is successfully
converted).
Cordially,

Very interesting! I have seen similar behavior these past days (I think
it's very recent) but thought it was something in my documents. Hans, MWE:
I have two test files, simply with
\starttext
Test
\stoptext
I try to concatenate the resulting pdf files with qpdf:
qpdf test1.pdf --pages test1.pdf test2.pdf -- result.pdf
And I get these warnings (though the resulting file appears to be OK):
WARNING: test1.pdf (xref stream: object 18 0, offset 4154): expected
