When deleting files in some folders within my home partition, all owned by me (with correct permissions, I guess) the tarsh folders ".Trash-1000" get created though theses are not external drives (nor mounted partitions)... 

While this is annoying it should still be fine when all these trashbins get collected in the nautilus trash bin. 

Opening "trash:/" should at least collect all the owners ".Tash-1000" trashbins and offer the option to delete them. 

But the common trash bin doesn't collect these trash bins at all. Deleted files do not show up within the nautilus window for the virtual folder "trash". Deleting leaves all the files in the "Trash-1000" in place... so there is no way of deleting them either than opening each one individually and removing the files within. 

I do not see how to fix this, I couldn't find any configuration files or configuration options for the trash bin, so I have no idea where to look or even how to start trouble shooting.
