Bug 163091

Version:           4.0.81 (using Devel)
Installed from:    Compiled sources
Compiler:          gcc 4.3 x86_64
OS:                Linux

When I login in KDE4 (4.0.80/4.0.81), I get a knotify4 crash pop-up dialog more than once a second, rendering my whole system unusable. I'm using Mandriva Linux Cooker x86_64.This is the stack trace:

Application: KNotify (knotify4), signal SIGABRT
Using host libthread_db library "/lib64/libthread_db.so.1".
