Comment 20 for bug 1576500

I don't think you actually have the same problem as us. See the picture attached to the bug report...if alt-f2 is working and krunner doesn't crash you probably have a different problem. I'd recommend opening a separate bug report with just your symptoms.

If you want to check if your problem is being caused by $XDG_DATA_DIRS, you can temporarily set $XDG_DATA_DIRS (all on one line):

XDG_DATA_DIRS="/usr/share" plasmashell

The symlink thing was a temporary workaround, I wouldn't actually recommend it. You can check that it's set properly by doing ls -l ~/.local/share/plasma
