Hi,
I have set the Gnus server variable `nntp-marks-is-evil' set to t
(default is nil). Occasionally, e.g. when there are network problems,
after hitting `C-g', this variable changes to nil and I get errors
(see blow: [1]).
I don't know why the variable's value is changed. Is the any way to
produce a backtrace when a variable changes? I run Emacs under gdb,
if that is relevant.
