DDD freeze

Hi,
Every few weeks after dozens of ddd sessions, ddd will start up in a state 
saying on the lowest panel of the terminal window:

   Disassembling location 0x.... to 0x....done


Clicking the "Break" button on the toolbar results in a message on the lowest 
panel of the terminal window:

   Break: waiting until GDB gets ready


I used to fix this by deleting ~/.ddd/init


I now found i just have to delete from within ~/.ddd/init, the line:

   set extended-prompt not set\n\


Obviously "not set" is not a valid parameter for "set extended-prompt".

DDD seems to have no maintainer. I might try and fix it one day.
