An upgrade might help. Avarice defaults to driving the jtag bitrate at 1
MHz and if your target is running at 4 Mhz or slower, this error is
common. See if your version of avarice has this option (using 'avarice
-h'):

  -B, --jtag-bitrate <rate>   Set the bitrate that the JTAG box communicate=
s
                                with the avr target device. This must be le=
ss
                                than 1/4 of the frequency of the target. Va=
lid
                                values are 1MHz, 500KHz, 250KHz or 125KHz.
                                (default: 1MHz)

If not, try upgrading and see if that helps.
