In bugs.kde.org we got a crash report about ipfire: https://bugs.kde.org/show_bug.cgi?id=271469
I checked the code and you are not setting a custom bugtracker address for the application, so it will fallback to bugs.kde.org:
You have to ways to specify a custom bug tracker in the code:
1) In the KAboutData constructor, set the 10th parameter to "http://sourceforge.net/tracker/?group_id=149121&atid=773762" (http://api.kde.org/4.x-api/kdelibs-apidocs/kdecore/html/classKAboutData.html#a95684a6725a286095710923c3fe8cdf8)
or
2) After the KAboutData constructor, call
aboutData->setBugAddress("http://sourceforge.net/tracker/?group_id=149121&atid=773762");
