Hi,
since some time, `timer-event-handler' messages error messages in case
of errors (when debug-on-error is nil). This is good!
However, in my experience these messages as such are currently not very
helpful. E.g I get a message like
| Error running timer: (error "Selecting deleted buffer")
Mmh.
I can try setting `debug-on-error' to t (which is a pain in the
ass as long as `user-error' is not very widespread, btw) and hope that
it "happens again". But it would be better if the message would be more
informative. E.g. we would win a lot with doing this:

It would at least reveal where I have to dig. Better ideas appreciated!

Looks good to me. Tho please use %S rather than %s.

AFAICS, equivalent code already was installed, 2 weeks before this
report was opened?

Indeed. But why don't I "have" this change in my "GNU Emacs 24.3.50.1
x86_64-pc-linux-gnu, GTK+ Version 3.4.2) of 2013-04-27 on dex,
modified by Debian" (i.e., emacs-snapshot)?
Michael.

Because I had used a local copy of timer.el in the meantime. It was
created before I had Stefan's change.
Thanks, Stefan and Glenn!

Michael.
