Evolution starts whenever I plug in or unplug the charger

[´silas]

So yeah basically what the title says. Whenever I plug in or unplug the charger, Evolution pops up and shows me this introduction screen. I guess that's because I didn't set up Evolution yet.
It's not that much of a problem really, but I'm just curious as to why this happens. I've reinstalled ubuntu several times, and it's the same all the time. Running Intrepid on Asus eee laptop.

Any guesses ? :D

Go to System>Preferences>Preferred Applications. Then click on the tab that says internet. Then look where it says mail reader. The default should be evolution. Reply with what it says is the command to start it.
