The fact that dpkg 1.0.6 - which is badly broken - is in the stable tree has been causing people problems.
I have therefore moved 1.0.5 out of Incoming myself and put it in stable/{binary,source}/base. I hope doing this without following whatever the normal procedures are won't cause problems, but it is important that no more people than necessary install 1.0.6. It looks like I forgot to upload the .nondebbin.tar.gz file; I'm uploading that now. Ian M., can you put it in its conventional place please, when it arrives ? Ian.
