Seems like it crashes as soon as the garbage collector is done once (see
attached patch). Just removing the "local" makes the crash go away here. I
didn't know that lua is this smart...

Attached is the patch that I tested this with. The error message on stderr was:
awesome: cairo-surface.c:905: cairo_surface_reference: Assertion
`((*&(&surface->ref_count)->ref_count) > 0)' failed.
In other words "this surface was already destroyed".
Hey Arnaud, do you have anything which is remotely similar to this issue in your
config? Could this explain your random crashes?
