[Roger Martinez <roger.martinez7@wanadoo.fr>]

Hello

i have problems with tar - GNU version of the tar archiving utility .
When i extract gzipped  file  , the  own file change alone

example  :  mozilla- 1.7.8.fr-FR......  .tar.gz  own file : root and the 
same for the group
after extract : tar -xvzf mozilla- 1.7.8.fr-FR......  .tar.gz   own file 
: roger  and the same with group

i tryed dpkg-reconfigure tar packet but it's  the same
it seems that problems live  since  1month  ago
all problems are only in /usr/local  partition  since  i upgrade  
debian  sarge


in /Usr/local Ihave firfox , mozilla , otp_srcR10B, jdk1.5 , wings-0.98 
,clamav-0.85 ...and these old install seems to have no problems

Can you help me please ?
