Your computer could have bad ram!
I get this error quite often.
It almost exclusively happens when I press the 'x' button on the window to close it. (Funnily enough.)
Instead of closing it states "An unrecoverable fault has occurred" (or something similar) with a read/write error, then it lets me close it.
A few times, it happened when I simply moused over the element categories to the right.
