synercy server daemon crashes on login

[Joh Man X]

Binary package hint: synergy

After upgrade from Jaunty to Karmic, i had 2 reboots. The one at the end of the upgrade, which went too smoothly, due to expected errors because of my homemade configuration for my graphics driver, and a second reboot this morning, when all of the sudden my synergy server went down for no reason on login.
Since the upgrade, i made only the slightest changes. I let Firefox import it's own settings, due to the upgrade from 3.0 to 3.5. Then i started watching some videos at YouTube and found out to have the screensaver timeout set to 5 minutes. I changed that, but nothing else, for i went to bed and woke up, booting in this state.

What i expected to happen:
No complaints from the synergy server daemon at all.

What happened instead:
Complaints from the synergy server daemon, one day after upgrading to karmic, with only the minor changes like screensaver timeout and importing firefox 3.0 settings to firefox 3.5.
