Created attachment 110317 [details] New crash information added by DrKonqi plasma-discover (5.10.5) using Qt 5.9.1 - What I was doing when the application crashed: Well, no applications were running but I can mention the suspicious things that I did before I tried opening Discover:- 1. I changed the sources.list file entries. I removed the country codes from all the exisiting entries to make them reflect to the main server and I added 4 lines for mirror in the beginning of the file:- deb mirror://mirrors.ubuntu.com/mirrors.txt precise main restricted universe multiverse deb mirror://mirrors.ubuntu.com/mirrors.txt precise-updates main restricted universe multiverse deb mirror://mirrors.ubuntu.com/mirrors.txt precise-backports main restricted universe multiverse deb mirror://mirrors.ubuntu.com/mirrors.txt precise-security main restricted universe multiverse 2. I changed my display driver to Nvidia driver from the default xorg one. 3. I changed the theme to Breeze Dark (I know it's stupid to write this as a suspicous thing, but whatever...) Also, one unusual thing that happens that I don't think is related to this, but just in case it is: When I run "sudo apt-get update", at the end of everything I get a few errors- W: GPG error: mirror://mirrors.ubuntu.com/mirrors.txt precise-updates InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 40976EAF437D05B5 E: The repository 'mirror://mirrors.ubuntu.com/mirrors.txt precise-updates InRelease' is not signed.

If rebooting after changing nvidia drivers does not fix the crashes, please ask for help in a forum of your distribution. The OpenGL drivers need to be installed correctly, including matching kernel and nvidia module versions.
