*** Bug 260931 has been marked as a duplicate of this bug. *** commit c6c086a80162d796f3cb2a692f516e092d4faa2c branch master Author: Volker Krause <vkrause@kde.org> Date: Wed Jan 12 16:02:46 2011 +0100 Fix crash when losing network while trying to connect a new session. In this case all already ready sessions disconnect, and with none left, the account object is deleted to prepare the full reconnect. The pending session then fails as well, at which point accessing m_account will crash.
