Summary: After copy the file is changed.

Initial Comment:
Hello,

I'm working with mysqlfs, and very interested. It could be a backup-back-end. 

But now I run into some problems:

after I mount it (with root privileges!) I've got a mountpoint:

mysqlfs on /tmp/mysqlfs type fuse (rw,nosuid,nodev)

Now I copy a file to it:

cp ~/download/linux-2.6.20.2.tar.bz2 /tmp/mysqlfs

this goes fine. But now I want to unpack it:
cd /tmp
tar -xvf mysqlfs/linux-2.6.20.2.tar.bz2 

I get the error:

tar: This does not look like a tar archive
tar: Skipping to the next header
tar: Archive contains obsolescent base-64 headers
tar: Error exit delayed from previous error

Now this is not ok. Then I do:

diff ~/download/linux-2.6.20.2.tar.bz2 \
     mysqlfs/linux-2.6.20.2.tar.bz2

Binary files differ.

How is this possible?

Is this a new error or....?

Message:
I just added revision 48, which includes a testcase that mounts the
filesystem and copies a file onto it, then compares the checksum.  Tested
with linux-2.6.30.tar.bz2, checksum was a match.

I'm shifting this to a "works for me", but I hope you're willing to come
back and offer more details, or check out rev 48 of the SVN and try it: 
./configure --with-testfile=linux-2.6.20.2.tar.bz2 && make check
