AC3 in Matroksa problem (with mkvmerge 4.2.0)

I'm trying put ac3 into an mka file using mkvmerge. Mkvmerge version 4.2.0 generates a file that foobar 1.0.3 can't play "Decoding failure at 0:00.000 (Unsupported format or corrupted file)". Mkvmerge version 3.4.0 generates a file that works fine. VLC plays both files. Is this an mkvmerge or foobar error?

Here are the commandlines that I am executing:

mkvmerge -o "audio mkvmerge 3.4.0.mka" audio.ac3
mkvmerge -o "audio mkvmerge 4.2.0.mka" audio.ac3

C:\Download\mkvtoolnix-unicode-3.4.0>mkvmerge -o "audio mkvmerge 3.4.0.mka" audio.ac3

foobar 1.1 beta2 supports matroska files created with newer versions of mkvmerge.

Perhaps that's due to the header removal compression which is default in the newer versions. In mkvmerge GUI visit the Extra options tab for the audio track and deactivate it and mux to verify that.

By the way: it's matroska, not matroksa.

The 4.2.0 test file uploaded plays fine in foobar2000 1.1 beta 2.
