Odd parse error on cron run

Could you tell me what it's trying to parse? Can you capture what's being passed to $read ?

I have something similar, but on node page, the string passed to read is an empty string. Actually, because of this error some nodes cannot be displayed.
Nodes have a geofield, and those throwing exception contain the following field:

field_coordinates (Array, 1 element) 
und (Array, 1 element) 
  0 (Array, 11 elements) 
    wkt (NULL) 
    geo_type (NULL) 
    lat (NULL) 
    lon (NULL) 
    left (NULL) 
    top (NULL) 
    right (NULL) 
    bottom (NULL) 
    srid (NULL) 
    accuracy (NULL) 
    source (NULL)

I assume this field doesn't contain what it should, because node was created by feeds after importing an CSV file, and that is causing the error.

To fix I added in the geofield_map.module, function geofield_map_field_formatter_view, on line 62
if (empty($item['wkt'])) continue;

So the code looks like

foreach ($items as $item) {
    if (empty($item['wkt'])) continue;
    $geometry = geoPHP::load($item['wkt'], 'wkt');
    ...
  }

Wow, so quick, I didn't even manage to edit my post...
I'm glad you are better !
