Fixed in revision 536458. There were at least three bugs:

  - KDevelop used "attach" and did not notice that we really attached 
  - When attaching, you'd use the symbol table of the program you've setup
    in debugger settings, not the one you've attached to.
  - Attaching to multi-thread programs did not work as you've reported above.
