Hello everyboy, my 1st bug I'm reporting here, give me some hints on what I do better.
My environment: I'm currently running KDE 4.3.5 on OpenSuSE 11.2. The QT version is 'libqt4-4.5.3-2.4.2.i586'. I have configured my incoming mail so that it is retrieved from my provider with fetchmail and passed to postfix. postfix does basic spam filtering and delivers the incoming messages to the local mailboxes in /var/mail -- so far everything is working just fine. My problem: Since upgrading to KDE 4.3.5 on SuSE 11.2 I'm experiencing the following problems with KMail / Kontact (applies to both). Previous versions of KDE (4.3.4 was last I had installed) did not show this problem. When Kmail picks up messages that have an attachment of any kind from the local mailbox, then KMail becomes unresponsive and starts to consume 100% CPU. This also happens when mails are ready to be picked up and Kmail is started. In the latter case the GUI is not drawn until the spook is over... Depending on the size of the attachment, it takes _hours_ (I've experienced more than 20 hours for a 500 KB attachment) until Kmail turns back to a usable state again and the mail finally becomes visible in Kmail's inbox. The problem is reproduceable at will with any mail with an attachment picked up from the local inbox. New mails which are delivered to the local mailbox during this 'heavy duty' task get picked up (i.e. they are removed from the local mailbox), but never appear in KMail. In fact these messages are lost. I have several times used gdb to attach to the KMail / Kontact process while the process was in this 'busy state' to produce a stack trace. All of these traces look similar to the following: prompt>ps -ef | grep kontact me 8215 1 7 20:47 ? 00:01:22 /usr/bin/kontact prompt>gdb -p 8215 GNU gdb (GDB) SUSE (6.8.91.20090930-2.4) [...stuff deleted...] Attaching to process 8215 Reading symbols from /usr/bin/kontact...Missing separate debuginfo for /usr/bin/kontact Try: zypper install -C "debuginfo(build-id)=980aec264983df3a787a141907cfea009a359d22" (no debugging symbols found)...done.

Only the few lines at the top (of the stack) varied slightly, some times with, some times without the 'QChar::toLower()' entry. Does this stack trace maybe help already to identify the problem? I have read the "How to create useful crash reports" guidelines, but I could not find any debug related packages for kmail, kontact and/or kdepim in the OpenSuSE repositories. If someone can point me to the required debug packages, I'd be glad to recreate the stack trace and whatever else is required with those installed. Thanks for any help! _______________________________________________ Kdepim-bugs mailing list Kdepim-bugs@kde.org https://mail.kde.org/mailman/listinfo/kdepim-bugs
