The question is

> #part type=#("text/plain" 0 10 (fontified nil)) filename="~/gdb.txt"
               ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^    

why the C-c C-a prompt delivers a string with text properties attached
in your case.  This should not happen, and I can't reproduce this.  Are
you using any package for completion, have configured completion, or do
you have any idea why a call like

  (gnus-completing-read
   "Content type"
   (mailcap-mime-types)
   nil nil nil "application/octet-stream")

does not return a plain string for you?
