- What I was doing when the application crashed:

This happens both when applying updates and uninstalling software. This particular crash came after attempting to uninstall backup software (what good is it if none of it can get to WD MyCloud?). Earlier today I crashed applying updates. I used Synaptic to install the required debug packages for Discoverer.

NEVER EVER USE QML for anything.
