nowcommons fails:
C:\pwb\GIT\core>pwb.py nowcommons -simulate Retrieving 30 pages from wikipedia:de. >>> Datei:Fraukirch Umgebung.jpg <<< No page is using "Fraukirch Umgebung.jpg" anymore. Traceback (most recent call last): File "C:\pwb\GIT\core\pwb.py", line 256, in <module> if not main(): File "C:\pwb\GIT\core\pwb.py", line 250, in main run_python_file(filename, [filename] + args, argvu, file_package) File "C:\pwb\GIT\core\pwb.py", line 121, in run_python_file main_mod.__dict__) File ".\scripts\nowcommons.py", line 485, in <module> main() File ".\scripts\nowcommons.py", line 482, in main bot.run() File ".\scripts\nowcommons.py", line 452, in run pywikibot.output(u'%s' % e[0]) IndexError: tuple index out of range <type 'exceptions.IndexError'> CRITICAL: Closing network session.
but the error is quite misleading. I repaired that line 452 (removing that index) and added an additional exception() call above. Then I get:
C:\pwb\GIT\core>pwb.py nowcommons -simulate Retrieving 32 pages from wikipedia:de. >>> Datei:Fraukirch Umgebung.jpg <<< No page is using "Fraukirch Umgebung.jpg" anymore. ERROR: NoPage: Page [[commons:File:Wdwdbot]] doesn't exist. Page [[commons:File:Wdwdbot]] doesn't exist.
which looks ugly. The corresponding template looks like {{NowCommons|transferby=wdwdbot}}. I guess that transferby is misinterpreted by the bot.
