Created attachment 63030 [details] New crash information added by DrKonqi kontact (4.7.0 ) on KDE Platform 4.7.00 (4.7.0) using Qt 4.7.3 - What I was doing when the application crashed: Open Kontact, summary page shows two mailboxes with unread mail, clicking one of them causes Kontact to crash -- Backtrace (Reduced): #7 0x00007f462047482d in QApplication::notify(QObject*, QEvent*) () from /usr/lib/libQtGui.so.4 #8 0x00007f4621af0226 in KApplication::notify(QObject*, QEvent*) () from /usr/lib/libkdeui.so.5 #9 0x00007f4621091bbc in QCoreApplication::notifyInternal(QObject*, QEvent*) () from /usr/lib/libQtCore.so.4 #10 0x00007f4620470142 in QApplicationPrivate::sendMouseEvent(QWidget*, QMouseEvent*, QWidget*, QWidget*, QWidget**, QPointer<QWidget>&, bool) () from /usr/lib/libQtGui.so.4 [...] #12 0x00007f46204eb10a in QApplication::x11ProcessEvent(_XEvent*) () from /usr/lib/libQtGui.so.4
My apologies; I marked the bug as occurring all of the time, when in fact it is only some of the time. Additional information: Only one specific mailbox causes the crash. Currently it is a locally-stored POP3 mailbox with 8 emails, 6 of which are unread. Clicking the mailbox from within Kmail (i.e. after click the mail tab on the left of Kontact) never causes a crash. Similarly, the second mailbox which is an IMAP account never causes a crash regardless of how I access it.
Thanks for the details. Unfortunately, I cannot reproduce with a recent Kontact version.
Please retry with a recent Kontact version (>=4.7.1)
