To recap my understanding here: To fix the bug in Maverick we need:
1. The patch from comment #8 in the kernel to enable protocol changes for rc5sz (I made some test packages for -generic and put those to http://people.canonical.com/~smb/lp663651/)
2. The changes from comment #2 (but with rc5-sz changed into rc5sz)
So would 1. and 2. be all needed or is the 90-streamzap.conf file still needed in that case?
