For some reason after running
apt-get upgrades, and maybe a few other things happened in between, on my installation of Kubuntu 15.04, KDE had stopped working the way it should. It started with a crash and the screen turned black. Visible was only the mouse cursor which I could move, and IM Contacts which I could move too. Unfortunately I was unable to start any other program from within it, there was no panel, nor could I Alt+F2 to open anything through a command.
After looking around, and installing a whole bunch of other Desktop Environments (DE) which for the most part had other issues I didn't like, I managed to fix it.
By removing everything in
~/.kde/, you basically are cleaning up and starting fresh. A reboot and it worked for me.
Note: well, not completely, in between I also purged my kubuntu-desktop with
apt-get purge kubuntu-desktop and reinstalled
apt-get install --no-install-recommends kubuntu-desktop, but I question if this was necessary at all.

Try wiping cache:
$ rm -rf ~/.cache
$ sudo apt-get install unity-lens-applications unity-lens-files
Issue is gnome-terminal has shortcuts which use the same combination to switch between terminal tabs. By disabling these, your commands will pass through to irssi/weechat and they will work properly.
Edit-> Preferences, navigate to
shortcuts tab and locate
Switch to Tab %d, [1~10]. Clicking on the shortcut and hitting
backspace will disable the shortcut.
