I am running Windows 7 RC, I have israeli locale set, with ooo3.1.0 m11
On linux I am generating 2 odt files, both in english.
1. simple document with "Hello World!" in it, let it be 1.odt
2. complex document with tables of images, paragraphs, etc. I'm generating it
with odfpy v. 0.7.0 package from wikipedia's NASA article, let it be 2.odt

ooo was installed on the system and I didn't touch the locale settings.
 * I tried to load document 2.odt, it crashed.
 * tried to load document 1.odt, it loaded, but it looked a bit reversed:
the sentence was aligned to the right, and the exclamation mark was on the left
hand.

Then, I played with the language settings, and have set English USA as the main
locale, and this has solved the problem.

I think the fact ooo is set to be in RTL/hebrew/arabic mode should not stop from
loading english documents.
