I forgot to mention that I checked for some of the corrupt files if they are corrupt on source.squeak.org and it seems they are not, e.g.

curl -O http://source.squeak.org/trunk/Collections-eem.571\(nice.569\).mcd
unzip -t Collections-eem.571\(nice.569\).mcd
Archive:  Collections-eem.571(nice.569).mcd
    testing: package                  OK
    testing: version                  OK
    testing: base                     OK
    testing: old/source.st            OK
    testing: new/source.st            OK
    testing: patch.bin                OK
No errors detected in compressed data of Collections-eem.571(nice.569).mcd.

It seems to follow that the corruptions happen locally because of broken (intermediate?) code which is executed during the trunk update.

Cheers,
Bernhard
