libreoffice helps me to log out ubuntu

Have you tried renaming the configuration folder for Libreoffice then starting it to get default settings

I renamed the folder ~/.config/libreoffice and opened a document with libreoffice and session went out in a second.

New libreoffice config folder was created.

I purged libreoffice-* and installed again.
Seemingly it helped for now.

Libreoffice keeps logout my session, please help me!

My env:
* Ubuntu 13.04
* Linux ubuntu 3.8.0-33-generic #48-Ubuntu SMP Wed Oct 23 09:16:58 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
* libreoffice 4.1.3~rc2-0ubuntu1~raring1~ppa1

I have tried all steps in @actionparsnip @lan1967, no any helps.

As you are using a PPA and not the Libreoffice from the official Ubuntu sources I suggest you email the maintainer to report the problem.

I bet if you remove the PPA using ppa-purge you will find it works.

Why did you add the Libreoffice PPA?

Bugs from the PPA are to be treated the same as bugs from the official package. All of them are to be reported either against the Libre Office project if they are from the PPA, or against the Libre Office package if they are from the ubuntu package.
