Opening a big key doesn't work

I have a big key database, but when I click on it, it doesn't show, there's just a blank window, where there should be paginated keys. I fixed it by increasing the memory for the file, but I don't know if it's the right way.

If that fixes it then I guess it ran out of memory while fetching everything, seems like a good fix.
