[Mediawiki-l] bug:<pre>-Tag corrupts texts in MediaWiki

Sat Feb 10 18:09:30 UTC 2007

Hello,

I have a fresh installation 1.9.2.

I created a new page with some text in it: 
http://beadsoft.net/wtest/index.php?title=Textloss&oldid=42

between the <pre>-tags I do have HTML-coding.

When I use the edit-function on a later section AND insert a new heading 
of the same level, the text of the whole article will be corrupted.

I had
* loosing text after the new section
* doubling of sections
* complete corruption

You are invited to play in my testwiki, see link above.

regards,
Gunter
