Comment 36 for bug 30842

GodXera: i recently(just now) had the same problem with my new kubuntu 11.10 installation.
When trying to delete an item I got the message:

     "The trash has reached its maximum size! Cleanup the trash manually."

and after deleting the folders

                                             ~/.local/share/Trash/
and
                                             ~/.local/share/Trash/info

I ended up with the error message:

     "Could not write to file ~/.local/share/Trash/info/filename.trashinfo."

After I have read your post I tried using Thunar too and that worked.

By accident I discovered that when you open the trash with Konqueror and rightclick where the deleted items normally would be you get access to a menu "Configure Trash Bin".
There I changed some settings and afterwards I was able to delete files with Dolphin and Konqueror again.
