Unset bug address for implicitly created KAboutData
When calling KAboutData::applicationData when setApplicationData hasn't been called before we create a new KAboutData and set that as global about data
That gets the default KDE bug report address
Since this is likely happening in a third-party app this is likely wrong and causes DrKonqi to try and submit it to bugs.kde.org
Manually unset the value to avoid that
