I saw this as well in my installation of v3.2 final at 
http://porpoisehead.net/gedview/

I think it's because the fontsize that is passed to the ImageTtfBbox 
function has contents something like "6px" when the function expects 
someting like "6.0".  I made a temporary fix.  I didn't bother sending it 
to the project because it's obviously a nasty kludge, and I expect it is 
fixed in more recent versions of the project.  The change is in the 
fanchart.php file, starting at about line 257:

   // calculate text position
   $dfontsize = str_replace("px", ".0", $fontsize);  // CHANGE: new line
   $bbox=ImageTtfBbox($dfontsize, 0, $fontfile, $text);  // CHANGED
   $textwidth = $bbox[4];
   $deg = $deg1+.44;
   if ($deg2-$deg1>40) $deg = $deg1+($deg2-$deg1)/11;
   if ($deg2-$deg1>80) $deg = $deg1+($deg2-$deg1)/7;
   if ($deg2-$deg1>140) $deg = $deg1+($deg2-$deg1)/4;
   if ($gen==0) $deg=180;
   $rad=deg2rad($deg);
   $mr=($rx-$rw/4)/2;
   if ($gen>0 and $deg2-$deg1>80) $mr=$rx/2;
   $tx=$cx + ($mr) * cos($rad);
   $ty=$cy - $mr * -sin($rad);
   if ($sosa==1) $ty-=$mr/2;

   // print text.  next line CHANGED 
   ImageTtfText($image, $dfontsize, $tangle, $tx, $ty, $color, $fontfile,
$text);


All the lines that have changed have a comment with CHANGED near them.
