Maybe this helps:

You are using a different view, so the behavior is different.

I use Basic Thumbnails, 8×4, AJAX navigation, add hidden pics, no javascript effect, “default-view.php”.

That’s all.

I guess that the filter function is broken and returns a very large object, so it kills the available memory.

No, still broken, checked on my test server.
On my life server I now use FooGallery which runs flawlessly.

I am sorry. It is not solved even when all other plugins have been disabled.
It seems that the script dies (it exhausted the existing memory) when WordPress starts to execute the filters. This is a problem in Nextgen 3.9.x. 3.8 has worked fine.

At the moment I can still check it on my test server but I mirror from time to time my live website to the test website in order to check other issues.

No. Still broken.
