Monger still gives a backtrace if you try to query a nonexistent module. Would be nice to have fixed before the next stable and should be easy to fix for anyone that has 10min free. Example:

% pike -x monger --query gazonk No such module gazonk. /usr/local/pike/7.6.117/lib/modules/Tools.pmod/Monger.pmod/MongerUser.pike:428: Tools.Monger.MongerUser()->xmlrpc_handler()->_caller()->`()("gazonk") /usr/local/pike/7.6.117/lib/modules/Tools.pmod/Monger.pmod/MongerUser.pike:196: Tools.Standalone.monger()->get_module_action_data("gazonk",0) /usr/local/pike/7.6.117/lib/modules/Tools.pmod/Monger.pmod/MongerUser.pike:165: Tools.Standalone.monger()->do_query("gazonk",0) /usr/local/pike/7.6.117/lib/modules/Tools.pmod/Monger.pmod/MongerUser.pike:123: Tools.Standalone.monger()->main(3,({"/usr/local/pike/7.6.117/lib/modules/T ools.pmod/Standalone.pmod/monger.pike","gazonk"}))
