I wouldn't be surprised if gimp-2.3 That's a good point!

That is most likely because your copy of gimp-2.3 has debugging symbols while your copy of gimp-2.2 doesn't. I wouldn't be surprised if gimp-2.3 uses a little more memory than gimp-2.2 but the difference should be marginal. > Each time I load an image then close the image window without doing > anything, gimp grows by some variable amount, ranging from half a > Mb to 2Mb (perhaps related to the size of the image).

I have tested this in valgrind and it doesn't show me any memory leaks. Can you reproduce this with G_SLICE=always-malloc ?

That's not a useful measure as it doesn't take memory pools into account. glibc has memory pools and gimp 2.3 also makes heavy use of GSlice. > So my questions are: > > - Is the growth that comes from loading an image, doing operations > on it then closing the window expected?

I would definitely be concerned but since I don't know what gmemusage does and since I don't know anything about the differences between your gimp 2.2 and gimp 2.3 installation, there's not much we can do. If you suspect a memory leak, you should use valgrind to verify that. And you should run gimp with G_SLICE=always-malloc when doing that.
