When I input certain data as the contents of a page, and I later go to edit the page, I get all sorts of weird behaviour, like:

- getting only the Title field
- getting no fields
- getting some html in the editor instead of the page contents

I am not sure of what exactly is triggering the bug, the following text should do it:

!Algunos hosts
!!Listado 1
|!NOMBRE|!IP|!MAC|!UBICACIÓN|
|a|192.168.1.1{{{<br/>}}}192.168.2.1|12:34:56:78:90:12|here|
|b|192.168.1.2|12:34:56:78:90:12|there|

|c|192.168.1.3|12:34:56:78:90:12|here|
|d|192.168.1.4|12:34:56:78:90:12|here|
|e|192.168.1.5|12:34:56:78:90:12|here|
|f|192.168.1.6|12:34:56:78:90:12|there|

Variations on it may produce different results.

Cheers,
