As for me, I use KDE4 and PIM 4 too. But there are some bugs still, and in production putposes, I use KDE3.

KMail3 crashes on trying to view the message, that has multiline From: header:

Code: Select all

pavel@katerina:~> QGArray::at: Absolute index 0 out of range
*** KMail got signal 11 (Crashing)
KCrash: Application 'kmail' crashing...

pavel@katerina:~>


the example of the header is (sory for large message, but I could not find how to attach file to the post):

Code: Select all

As I have understood, nobody will do something with KMail from KDE3. The discussion of the bug is there: https://bugs.kde.org/show_bug.cgi?id=186176
