Under stock redhat 6.0, using gnome, the supplied enlightenment binaries leak memory like a sieve with a hole in it. I'm using all stock supplied packages, and gnome with the marble 3d theme. It seems that when I change desktop areas (goto left desktop or right, etc.) that the binary's size grows, and it never seems to go down. gnomepager seems to grow along with it. Restarting E helps, but doesn't reduce gnomepager's size. This is REALLY annoying, as I need to log in and out to fix the whole problem.
I've noticed this as well. Running Xvnc, under the gnome desktop, the image grows massively every time I just select a menu. Within a matter of minutes, the resident image is so big, I have to shut down and restart the server. This does not happen under KDE.
We are aware of several GTK themes that have memory leaks. Try changing the GTK theme and see whether you still get the E memory leak. In the test lab we have not seen leaks from E alone, only when combined with leaky themes and applications. Reopen the bug if you are still having problems.
