Created attachment 69312 [details] stack trace I am running kmail/kontact 4.4.11 from debian experimental. I typically just start kmail. Trying to retrieve mail from 2 accounts (imap from MS exchange and pop3 (gmx.net)), kmail segfaults with about 25% probability either after closing the kde wallet dialog or one of the dialogs that prompt for passwords directly. I suspect that the same error also occurs spontaneously sometimes when these accounts are checked automatically for new mail. I have had kmail crashing on my while I was typing a message, but it also just went away. Things improved by setting longer intervals between automatic checks. For me this version is basically unusable. I'll send some terminal log when I get the next crash. - System Information: Debian Release: wheezy/sid APT prefers testing APT policy: (990, 'testing'), (500, 'unstable'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 3.2.0-1-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages kmail depends on: ii kdebase-runtime 4:4.7.4-1 ii kdepim-runtime 4:4.4.11.1-3 ii kdepimlibs-kio-plugins 4:4.7.4-1 ii libakonadi-contact4 4:4.7.4-1 ii libakonadi-kde4 4:4.7.4-1 ii libc6 2.13-27 ii libgcc1 1:4.6.3-1 ii libgpgme++2 4:4.7.4-1 ii libkabc4 4:4.7.4-1 ii libkcal4 4:4.7.4-1 ii libkcmutils4 4:4.7.4-1 ii libkde3support4 4:4.7.4-1 ii libkdecore5 4:4.7.4-1 ii libkdepim4 4:4.4.11.1+l10n-1 ii libkdeui5 4:4.7.4-1 ii libkhtml5 4:4.7.4-1 ii libkimap4 4:4.7.4-1 ii libkio5 4:4.7.4-1 ii libkldap4 4:4.7.4-1 ii libkleo4 4:4.4.11.1+l10n-1 ii libkmime4 4:4.7.4-1 ii libknotifyconfig4 4:4.7.4-1 ii libkontactinterface4 4:4.7.4-1 ii libkparts4 4:4.7.4-1 ii libkpgp4 4:4.4.11.1+l10n-1 ii libkpimidentities4 4:4.7.4-1 ii libkpimtextedit4 4:4.7.4-1 ii libkpimutils4 4:4.7.4-1 ii libkresources4 4:4.7.4-1 ii libksieve4 4:4.4.11.1+l10n-1 ii libktnef4 4:4.7.4-1 ii libmailtransport4 4:4.7.4-1 ii libmessagecore4 4:4.4.11.1+l10n-1 ii libmessagelist4 4:4.4.11.1+l10n-1 ii libmimelib4 4:4.4.11.1+l10n-1 ii libnepomuk4 4:4.7.4-1 ii libphonon4 4:4.6.0.0-1 ii libqt4-dbus 4:4.8.0-1 ii libqt4-network 4:4.8.0-1 ii libqt4-qt3support 4:4.8.0-1 ii libqt4-xml 4:4.8.0-1 ii libqtcore4 4:4.8.0-1 ii libqtgui4 4:4.8.0-1 ii libstdc++6 4.6.3-1 ii libthreadweaver4 4:4.7.4-1 ii perl 5.14.2-7 ii phonon 4:4.6.0.0-1 Versions of packages kmail recommends: ii gnupg-agent 2.0.18-2 ii gnupg2 2.0.18-2 ii pinentry-gtk2 [pinentry-x11] 0.8.1-1 Versions of packages kmail suggests: pn clamav | f-prot-installer <none> pn kaddressbook 4:4.4.11.1+l10n-1 pn kleopatra 4:4.4.11.1+l10n-1 pn procmail 3.22-19 pn spamassassin | bogofilter | annoyance-filter | spambayes <none>
Created attachment 69325 [details] a second stack trace this is a second stack trace taken after a 'spontaneous' crash a while after startup and successful first mail retrieval. Please note that the trace seems to refer to retrieval from a pop account, which in this context was located behind a firewall and thus inaccessible. #16 0x00007f88dc35cdf0 in KMail::PopAccount::qt_metacall (this=0xe04f70, _c=QMetaObject::InvokeMetaMethod, _id=<optimized out>, _a=0x7fff46cb6890) at ./popaccount.moc:83

This version is now unmaintained. Please consider upgrading to KDE >= 4.8.1
Thank you very much for this so helpfull answer. 4.7 is 9 month old and it took this time to the debian kde team to be able to package this. According to distrowatch, I have the choice between Arch and Gentoo to get 4.8.1...
