arises from a badalloc catch in qdebug - you're indeed out of memory. the
reason in the Xorg leak. Though this is likely a bug in the nvidia driver, you
could check whether it derives from high resource (pixmap) usage (as
gimp+digikam+composited(?!) kwin could induce)
start "xrestop" and have a look at the (rising) pixmap allocations and where
they source.

If you've got some sort of shared memory GPU it could also be nvidias pixmap
cache which is known to flood (caused by sth. in kdelibs...)
in this case calling
    nvidia-settings -a PixmapCache=0; nvidia-settings -a PixmapCache=1
from time to time resets (and frees) the cache (also providing speed
improvements)
