i tried today but couldn't find any problems (i did some benchmarking
with loading 2 images several 1000 times alternatingly). leaktracer
reported 288038 bytes being not freed (but this also happens when i was
just loading the images a few times)

there is a possibility that the memory leak is in the caching done by
[pix_image] (the cache could go infinitely large), which is not
triggered when just loading 2 different images.

anyhow, could someone send a small patch that is known to leak ?

i just noticed that there was a HUGE leak in [pix_buffer]'s
"open"-message (not freeing the memory of the loaded image after the
data was copied into the pix-buffer)

however, i have fixed that (in the CVS)

i haven't found any other leak (there is no caching done in pix_buffer,
so i guess my assumptions are true even for 10000 different images)
