seems to be a bug in the MarkDown parser of Indefero triggered by content.

PlufErrorHandlerException making GET request to /p/letux400/page/GPIO/
8 : Undefined offset: 3

* PlufErrorHandler
       [/Library/WebServer/Sites/projects.goldelico.com/pluf/src/Pluf/Text/MarkDown.php, line 2244] *

2239:         # Write column headers.
2240:         $text = "<table>\n";
2241:         $text .= "<thead>\n";
2242:         $text .= "<tr>\n";
2243:         foreach ($headers as $n => $header)
>> 2244:             $text .= "  <th$attr[$n]>".$this->runSpanGamut(trim($header))."</th>\n";
2245:         $text .= "</tr>\n";
2246:         $text .= "</thead>\n";
2247:         
2248:         # Split content by row.
2249:         $rows = explode("\n", trim($content, "\n"));

So it seems to have something to do with table header formatting.

And most likely Indefero was developed / tested on a system where an undefined offset
index did not raise errors.

Maybe I can patch / fix the problem in Indefero or at least make it
not fail completely.
