This error occurs when getting the abstract from the modified MediaWiki fails three times (line 134 in AbstractExtractor). The actual error messages from these three tries are (or should be) written to the log file (line 128). These actual error messages would be very helpful. Could you send them to the list? Maybe you have to turn on logging first, I'm not sure.
