Version: KDE 4.4.0 (using KDE 4.4.0) Compiler: Intel quad with 8gb ram and 64 bit version of Kubuntu Karmic with KDE 4.4 OS: Linux Installed from: Ubuntu Packages Kmail freezes kontact when emails are send for up to 1 min which is totally unacceptable. This in the new 4.4 version and after futher research determined to be caused by nepomuk. When nepomak is turned off, the sending is instantly. This is a serious problem which needs urgent attention as it makes the system unusable and too slow.
