REVISION SUMMARY Observed with a crashing KDevelop: If the QApplication is destructed after cleanup of the DrKonqi backend, somehow a DrKonqi-thread of the QDBusConnection may be blocked by the debuggee (poll() being stuck according to strace). Since DrKonqi then cannot quit, KCrash continues waiting, leading to a deadlock. The situation may be disentangled by externally sending SIGSTOP to the debuggee. Cleaning up the QApplication first and afterwards the backend omits the deadlock. TEST PLAN - let kdevelop crash to fire up DrKonqi - close DrKonqi again - watch state of crashed kdevelop process REPOSITORY R871 DrKonqi BRANCH scopedqapp REVISION DETAIL https://phabricator.kde.org/D18245 AFFECTED FILES src/main.cpp To: croick Cc: plasma-devel, sukalyanbanga, jraleigh, GB_2, ragreen, Pitel, ZrenBot, lesliezhai, ali-mohamed, jensreuterberg, abetts, sebas, apol, mart
