Yes. Either use `org-beamer-mode' or use #+STARTUP: beamer in your org
file.

[O] Emacs hangs sometimes for no reason

[Sebastian Christ]

Hi list,

in the last couple weeks (perhaps months?) Emacs hangs for no specific
reason for me. The single constant is, that when it hangs, it hangs
while I'm in org-mode. This occurs on multiple circumstance as

- changing the outline structure by demoting and promoting headline
- when refiling
- re-schedule in agenda
- yanking
- perhaps more

The strange thing is that it happens unpredictably, e.g. I re-schedule
11 items without problems and the 12th one lets Emacs crash. Sometimes
it works for days without problems and then I promote a headline and
Emacs crashes. Very sad :(

When I kill Emacs with

  $ pkill -SIGUSR2 Emacs

this leaves me in the Emacs debugger in a flyspell function or (today)
in a avl-tree function.

My actual question is, had someone had similar issues? Or is it just me
with my configuration?

Perhaps someone can guide me on how I can find the root cause for this?
I pretty much lost here.

Thanks in advance for any hints.

Best,
Sebastian

You need to load `ox-koma-letter' and make sure you're not using the
latex exporter. For letters there is (after loading `ox-koma-letter' of
course) a separate koma exporter.

Sebastian

I can't actually help in using the letter class, but have you checked
"Creating letters with KOMA-Script scrlttr2 and Org-mode" [1]? I've been
using it excursively for all  my /formal/ letter writing and it works
great. Maybe you can give that a try? Plus it produces really nice
letters :)

Actually, I'm quite surprised that is working for you. According to the
file variables you enable lexical bindings. This prevents the recursive
call to "find_duplicates". This symbol isn't visible in the lambda.

Can you double check that `lexical-binding' is really non-nil?

Best,
Sebastian

P.S.: Do you know about `flet' and `labels'?

In this peculiar case, yes. But, at least for me, I use each for a
different purpose that doesn't duplicate the information. I'm using
org-ref for references and most of the time a more meaningful
caption. For example:

#+caption: A class with a main method
#+name: lst-main
#+begin_src java

Hi Aaron,

thanks for the tip with (org-element-property :value X). I also got rid

submitted another patch to fix that. But unfortunately it seems it got
lost in the interwebs.

Hi Kyle,

you're completely right. This is a bug in the provided patch. I've

I've submitted an new patch already.

I thought it would be better to change as little as

change that.

And of course,
