Internal Error during decoding

[anonymous]

Narcissus does not work due to an internal error.

Trac detected an internal error:

UnicodeEncodeError: ('ascii', u"= Wilkommen zur Beere-Projektseite des Team 9/18 im Sopra 2009/2010 =\r\n\r\n== RSS Feeds zur Projektseite ==\r\n * [.../sopra/timeline?ticket=on&changeset=on&milestone=on&wiki=on&max=50&daysback=90&format=rss \xc4nderungen an der Projektseite] ''es sollte reichen diesen Feed zu abonnieren''\r\n * [.../sopra/log/?format=rss&limit=100&mode=stop_on_copy \xc4nderungen am Repository]\r\n * [.../sopra/report/1?format=rss Aktive Tickets]\r\n\r\n== Tools ==\r\n * [wiki:svn Subversion(svn) Hilfe]\r\n\r\n== Programmierung ==\r\n * [wiki:JavaConventions Programmierkonventionen]\r\n * [wiki:JavaDoc JavaDoc]\r\n\r\n== Output zu Teammeetings ==\r\n * [wiki:Output28_01_10 Meeting 28.01.10]\r\n * [wiki:Output05_02_10 Meeting 05.02.10]\r\n * [wiki:Output08_02_10 Meeting 08.02.10]\r\n * [wiki:Output09_02_10 Meeting 09.02.10]\r\n\r\n== Tagebuch ==\r\n * [http://spreadsheets.google.com/...]\r\n\r\n== Hilfe zu Trac und zum Wiki ==\r\n * siehe [wiki:TitleIndex]", 232, 233, 'ordinal not in range(128)')
