I have identified why this error occurs. There was a misconfiguration in my apache config file that prevented the bot from accessing api.php. However, it remains a mystery why login.py is recursively coded. Generally, recursive calls are best avoided in anything other than academic software (e.g., computing small factorials). If it is necessary to use them, then there should be limit check on the number of recursions (and an error exit when this limit is exceeded). So, I still believe there is a problem with login.py that requires attention. It was my intention to file a bug with the pywikipediabot bug tracker, but my attempt to analyze the problem failed. I installed the python plug- in to Netbeans and traced the execution flow. However, when I reach the statement (at line 180 in login.py): response, data = query.GetData(predata, self.site, sysop=self.sysop, back_response = True) I attempt to step in without success. So, I can't identify the problem in detail. (This isn't helped by the fact that I am not really all that familiar with the python programming language). Since the recursion appears to occur through this call to GetData, my bug report would not contain much useful information. I would appreciate any advice how I should report this problem (other than simply documenting here).
