>From the elisp manual (node: Text Properties):
Each property has a name and a value. Both of these
can be any Lisp object, but the name is normally a symbol.
Well, it seems that when the Lisp object is not a symbol,
there is a problem. This is illustrated by evaluating
the following form interactively:
(progn
(put-text-property (point) (1+ (point))
'(example name)
t)
(put-text-property (point) (1+ (point))
'(example name)
nil)
(text-properties-at (point)))
If emacs crashed, and you have the emacs process in the gdb debugger,
please include the output from the following gdb commands:
`bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/Users/jcorneli/emacs/etc/DEBUG for instructions.
