Compress seems to not work

[dejawho]

Hi, when open my data.unity3d, modify it and save, the bundle is saved with my modification but since it is uncompressed it is really big. I've tried to hit compress but nothing happen

It also fails on some data.unity3d to uncompress for me... Keeping 2.2 binary too for these tasks.
