[Xfce-terminal] Cannot remove entries from history

[Peter Nabbefeld <peter.nabbefeld@xxxxxx>]

Hello,

I've got the following rather suspicious problem with xfce-terminal:
After removing entries from the history (using "history -d" or "history 
-c"), the entries are obviously buffered. When I close the terminal and 
the open another, the history is available again - for some reasons I do 
see this as a security risk. Can I remove the buffered entries somehow?

Kind regards

Peter
