segmentation fault importing calendar entries

[Jan Schneider]

Hi,

I'm just writing a module for importing Outlook/vCalendar entries into 
kronolith.

But when I try to insert more than one entry at once I get a segmentation 
fault. This is the backtrace:

Program received signal SIGSEGV, Segmentation fault.
0x4010be15 in strcasecmp () at ../sysdeps/generic/strcasecmp.c:72

What I do is basically a foreach loop with this code:

$event = array();
$event['title'] = ...
$event['description'] = ...
$event['location'] = ...
.
.
.
$eventobj = $calendar->getEventObject();
$eventobj->readFormData($event);
$eventobj->save();

The crash occurs when readFormData is calling mcal_event_add_attribute to set 
the location. The locations are "Deutschland" and "" (empty string).

Any idea?

Jan.
