[Bug 1540830] [NEW] After Plasma 5.5.3 - apt-check causes massive load / creates 100's of processes

[yossarian_uk]

Public bug reported:

Since upgrading to Plasma 5.5.3 (via 15.10 backports PPA) every morning
my machine is unusable.

This morning the load was over 100 on my desktop - there were hundreds
of apt-check processes, plasma had completely crashed bar one konsole
window.

I have to sysRq to reboot...

Looks like others are having similar issues
