Are you sure that self.getfilepath() is a string? peterbe@trillian:~ $ python Python 2.4.3 (#2, Apr 10 2006, 11:53:13) [GCC 4.0.3 (Ubuntu 4.0.3-1ubuntu4)] on linux2 Type "help", "copyright", "credits" or "license" for more information.

From ExternalMethod.py:
152: def reloadIfChanged(self): # If the file has been modified since last loaded, force a reload. ==> ts=os.stat(self.filepath())[stat.ST_MTIME] if (not hasattr(self, '_v_last_read') or (ts != self._v_last_read)): self._v_f=self.getFunction(1) self._v_last_read=ts
Any idea what is causing this error. Looks to me to be a Python Bug. A bit of Googling shows this error showing up in a number of different contexts. Any suggestions for a workaround?
