I don't understand your code here. I DO get the error message, on the first time this entity is removed. Which, in my eyes, makes sense, because as soon as ent_remove is (successfully) called, me is set to NULL and tmpE is not, so outside the while loop tmpE != me is always true.

I posted the issue in the "ask the developers" forum. See here: http://www.opserver.de/ubb7/ubbthreads.php?ubb=showflat&Number=396146#Post396146
