so, now i found a third version of html.py (which is probably the one that is used, as there is also some bytecode files there) in 

/usr/lib/python2.4/site-packages/buildbot/status

and somehow managed to crash the twisted server with the following stacktrace in the master config:


2006/03/15 20:02 CET [HTTPChannel,0,127.0.0.1] Traceback (most recent call last):
	  File "/usr/lib/python2.4/site-packages/twisted/protocols/basic.py", line 221, in dataReceived

	    text.append("<a href=\"%s\">%s</a>" % (url, html.escape(name)))
	exceptions.AttributeError: 'str' object has no attribute 'append'


although i reverted all the changes i made (only th eline you told me in html.py)


the master is still running, but instead of the waterfall i get an even longer, more colorful and more complicated stacktrace.


apparently it is necessary to have a good python knowledge (which i don't so far) in oeder to work properly with buildbot.



any ideas on how i get out of this mess? O_o


thx in advance,
