Every few seconds kactivitymanagerd adds the following to the xsession-errors file. According to kdebugdialog kactivitymanagerd has debugging disabled.

Information value = zero after the first appearance. Danger of filling up /home and causing data loss.

Reproducible: Didn't try

Steps to Reproduce:
Disable nepomuk and restart KDE.

Actual Results:  
- Spamming xsession-errors with useless info
- Wasting resources
- filling up /home if the session is only suspended but "never" restarted, resulting in data loss

Expected Results:  
Report once and after that either keep quiet if not able to handle the situation without spamming the hard disk – or use methods like "the last messsage was repeated xyz times and write to xsession-errors less frequently and less text, i.e. as opposed to dozens.
