Comment 11 for bug 151045

Ok, with a irc chan and a good user, I found and this is not a bug :

ldd /usr/lib/libxml2.so.2
        linux-gate.so.1 => (0xffffe000)
        libdl.so.2 => /lib/tls/i686/cmov/libdl.so.2 (0xb7ec5000)
        [b]libz.so.1 => /opt/matlab/bin/glnx86/libz.so.1 (0xb7eb4000)[/b]
        libm.so.6 => /lib/tls/i686/cmov/libm.so.6 (0xb7e8f000)
        libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0xb7d45000)
        /lib/ld-linux.so.2 (0x80000000)

As you can see, libz is linked to the matlab one (I recently installed it) and this is the cause to my pb... This is the end of 2 days of heavy searches for this problem ! The solution is to unset LD_LIBRARY_PATH for the matlab path and add it just when launching / linking to matlab libraries....
