When activated the rune (probably due to the block breaking) turns all ic2 machines in range into invalid blocks http://i.imgur.com/OiOJKLW.jpg when broken the blocks turn back to normal and the bug doesn't happen again if the rune is broken and re activated (probably cause it hasn't got blocks to break)
sometimes takes a few tries to occur or a right click on the machine
relogging seems to fix it entirely though
the log says nothing but ic2 has a debug item that spews out some info that might be helpfull
there is also a pretty good chance that this is ic2s fault thus I linked this on their bug tracker http://bt.industrial-craft.net/view.php?id=1909
