>Description:
Some days ago I have done a dump of my /usr file system with:

# dump -0auL -P "ssh guru at albatros 'gzip -c > dumpsRebelion/usr.dmp.gz'"  /usr

the DUMP ended fine with no errors; today I try to reload certain
directory with:

$ restore -xv -P "ssh guru at albatros 'gzip -dc dumpsRebelion/usr.dmp.gz'" ./home/guru/myThings/Espanol/diario2008

and it says:

Verify tape and initialize maps
Tape block size is 16
Header with wrong dumpdate.
Dump   date: Mon Aug 25 09:56:58 2008
Dumped from: the epoch
Level 0 dump of /usr on rebelion.Sisis.de:/dev/ad4s1f

Extract requested files
You have not read any tapes yet.
If you are extracting just a few files, start with the last volume
and work towards the first; restore can quickly skip tapes that
have no further files to extract. Otherwise, begin with volume 1.
Specify next volume #: 1
partial block read: 16128 should be 16384
partial block read: 256 should be 16384
partial block read: 16128 should be 16384
unknown tape header type 6697331
abort? [yn]

the DUMP itself seems to be OK because this works:

ssh guru at albatros 'cat dumpsRebelion/usr.dmp.gz' | gzip -dc | restore -xv -f - ./home/guru/myThings/Espanol/diario2008

the problem seems to be -P related
