[Solved]Half my icons turned into red exclamation marks
 

I don't know what happened, ether it was a text that I got or it was my phone connecting to Qt, but now half my icons are red exclamation marks and unusable. The effect is not limited to third party apps, half a dozen Nokia apps have gone red to.

Can you help? I don't want to have to flash my phone.

Edit: Solved by doing a "apt-get -f install" in the terminal.
