file-meter: custom format not working correctly

[rgr-rgr]

    {
     "enabled" : true,
     "protocol" : "file",
     "path" : "/sys/class/thermal/thermal_zone0/temp",
     "format" : "$v",        /* a format string for parsing complex logfiles */
                             /* arbitrary text and whitespaces are  allowed, see 'scanf()' */
                             /* at least $v has to be used */
                             /* $i => identifier, $v => value, $t => timestamp */
     "rewind" : true,        /* reset file pointer each interval to  the beginning of the file */
     "interval" : 2,         /* of ommitted, we will try to listen on changes with inotify */
     "identifier" : "dummy",
     "channel" : {
             "uuid" : "f6ff48d0-aeac-11e3-b2ed-3bbb8f66a68d",
             "middleware" : "http://localhost/middleware.php"
             }
     } // meter

result:
[Mar 18 16:20:06][] MeterFile::read: 32, 32
[Mar 18 16:20:06][] MeterFile::read: '32552'
[Mar 18 16:20:06][] MeterFile::read: -0.000000, ▒, 0
[Mar 18 16:20:06][mtr1] Got 1 new readings from meter:
[Mar 18 16:20:06][mtr1] Reading: id=▒/StringItentifier: value=-0.00 ts=0.000
[Mar 18 16:20:06][chn1] ==> number of tuples: 0

The file contains "32552".

I expected that $v would contain "32552".
