Created attachment 36756 [details] Crash output on stdout I just recently started to set up UPNP extensions on my Linux router, and have noted that since the configuration is incomplete, konversation crashes when UPNP discovery is enabled because it cannot retrieve the upnp/control/WANIPConn1 file from the router. As this is a crash of the application instead of a harmless error message, I figured I'd put in the bug for it. Near as I can tell, instead of gracefully allowing the application to continue on it's merry way and attempt a fall back, the UPNP support is raising an exception and taking the app with it. Can we please change this to a nag message instead of crashing out? Attached is the console output from the crash. Thanks.

Gary, Thanks for the report. I'd like to be able to reproduce this locally. Do you have a copy of the incomplete config you were using for your upnp service that you can attach? - Michael
Also, which version of Qt are you running?
Created attachment 36907 [details] Test fix Please try the attached patch and let me know if it solves the crash.
Yes, that patch fixes the crash :) LGTM :)
