> This is a feature request to improve the situation around debugging safe
> hooks. Right now if an error occurs in a safe hook occurs, only a brief
> message is shown (safe_run_hooks_error in keyboard.c, "Error in %s (%S):
> %S"). Would it be possible to dump a stack trace to the *Messages*
> buffer? The problem is likely to avoid flooding the *Messages* buffer.
> On the other hand, hooks which throw errors are disabled anyway?

We have backtrace-on-redisplay-error, does that help?  If not, perhaps
a similar feature?
