[koinovi]

Ubuntu server 12.04 64-bit
16G RAM
1T HDD
When I add new torrent file in Deluge, I see in "Tracker Status": tracktor.in: error: invalid encoding of tracker response: "6D0x0d 0x0a d8:intervali3329e12:min intervali3329e5:peers60:0x05 0xffffffa7 0xffffffcb =0xffffffa9 0xffffffcf 0xffffffbc 0xffffffba 0xffffff9a 0xffffff92 c|0xffffffb0 0xffffffd6 0xffffff96 `sZ\0xffffffff 0xffffffaf 0x0c 0xffffffb0 -0xffffffbc 0xffffffba l0xffffffb9 ^0xffffffe8 [0xffffff90 0xffffff81 C0xffffffc2 0x03 0xffffffbc 0xffffffba 34A.0xffffffbc 0xffffffba 'i0xfffffff1 0x1c 0xffffffb0 0xffffffd6 0xffffff94 30xfffffff1 x0x05 0xffffffa7 0xffffffde 0xffffffd0 0xffffff99 de0x0d 0x0a 00x0d 0x0a 0x0d 0x0a "
