Why should I trust the "System program problem detected" dialog?

Solution 1:

You're absolutely right, there is a possibility that this is some other software masquerading as Apport (the bug reporting software).

I wouldn't worry about it though, as this is the expected behaviour of Apport. If you have it enabled and a program crashes, a window similar to this will appear. Sometimes Apport needs to run as root to gather system information and send it to Launchpad.

If you don't want to run this risk, just disable Apport.

If you do decide to trust this prompt, you'll be able to inspect the report and find out which program is crashing on login.

To disable Apport:

1. Press Alt + F2
2. Type gksu gedit /etc/default/apport and press Enter.
3. Replace the line enabled=1 with enabled=0.
4. Save and exit. You might have to reboot for the setting to come into effect.

Solution 2:

On terminal :

sudo rm /var/crash/*

this will delete old crash files. And then restart your computer. If still you see this dialog try these :

apt-get update
apt-get upgrade

(these are upgrade your packages with fresh ones) and restart.
