+> update 2014-06-29: the problem persists, but i found it is not trivial to
+> reproduce. to demonstrate, use this test plugin:
+>
+>     #!/usr/bin/env python
+>     # -*- coding: utf-8 -*-
+>     
+>     from proxy import IkiWikiProcedureProxy
+>     
+>     def preprocess(self, proxy, *args):
+>         return repr(self.rpc('pagetype', 'schön'))
+>     
+>     proxy = IkiWikiProcedureProxy(__name__)
+>     proxy.hook('preprocess', preprocess, id='testdirective')
+>     proxy.run()
+>
+> note that when the 'schön' is stored in a variable, the exception changes --
+> it seems to me that the issue is related to the way exceptions are encoded.

+> the suggested patch still applies and solves the issue. --[[chrysn]]
