In a plugin, let's say I download the page 'http://www.apage.com/path' using xmlws. If this page does a redirection to path '/redirect', Picard will attempt to load page '/redirect' instead of 'http://www.apage.com/redirect'.

I can reproduce this with any page on anidb.net that does a redirection.

To fix it, I added the following monkeypatch to my script (all pages have the string 'animedb.pl' in the path, so I use that to detect this bug).

if not hasattr(QUrl, 'orig_toString'):
	QUrl.orig_toString = QUrl.toString

def qturl_toString_monkeypatch(self, options = QUrl.None):
	if 'animedb.pl' in self.path() and 'anidb.net' not in self.host():
		log.debug("QUrl.toString Monkeypatch fired!")
		self.setHost('anidb.net')
		if 'perl-bin' not in self.path():
			self.setPath('/perl-bin/%s' % self.path())
	
	return QUrl.orig_toString(self, options)
	
QUrl.toString = qturl_toString_monkeypatch

Of course, fixing this directly on the xmlws redirect handler would be better.
