Re: Need help to find origin of a memory leakage

Finaly catch the memory leak I was fighting with Was a tricky one, but the solution was simple: I had to include the contents of the notebook tab in a frame. Otherwise the memory is not released when you remove the tab. Any idea why is it like that??? Could it be kind of pygtk bug? I attach

were group "Python 2.4" bugs ported over to the new bug tracker?

This bug about a urllib2 urlopen memory leak is still present but I don't see it in the new bug tracker anywhere: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1208304&group_id=5470 If this one is missing, presumably there are others? -gps -- http://mail.python.org/mailman/listi
