I cannot delete files through the file browser. Everything looks normal but the file is not deleted.

With --debug I get the following output. It starts from the moment I right-click the file to the moment after the dialog is acked with "OK".
My trash is empty and in Dolphin I see that it is set to a size of ~3GB.

Since KDE_LANG=en_US does not seem to have an effect here, there is German text in the output. It says "Trash has reached its maximum size. Please empty it manually."

Any idea?
