27.12.2008: Bug with content_excerpt in Habari 0.5.2

There seems to be still a bug in Habari 0.5.2, related with Format::summary and $post->content_excerpt. More information about this can be found in the following mailing list thread: http://groups.google.com/group/habari-users/browse_thread/thread/d2565ef99c5b7d51

Basically the characters > and < are not handled properly by this function, thus outputting the error message "Notice: Undefined offset: 1 in system/classes/format.php line XYZ" and as a result of this, not being able to display the rest of the site properly.

I'm currently temporarely using an own function implemented into the custom theme class for compiling an excerpt of the content of the specific post till the next stable version is coming out, hopefully including a fix for this.
