[Orgmode] error when exporting org to html

[Rainer Stengele]

I have a problem exporting html and directly browsing the exported file.
I have my org file in a indirect buffer,

Pressing "C-c C-e b" results in:

Exporting... [2 times]
save-restriction: Args out of range: 0, 1

org version: 6.21b
GNU Emacs 23.0.60.1 (i386-mingw-nt5.1.2600) of 2009-01-12 on LENNART-69DE564
(patched)

Can anybody give me a hint?


By the way, I always run into this task:
I have a very large org file and want to export a specific region to html.
The highest org-level of the region is for example "6" "******".
Exporting results "correctly" in "high" HTML header levels and "strange"
formatting formatting.
I would like to automatically export to "level 1".
What I now do is copy the region in a new org file. move the level to "1" = "*"
and export then. Bad workaround ...
Anybody has a suggestion?
