After adding some notes to a page on
http://wiki.splitbrain.org, I checked the spelling by pressing the spell checker button.
Returning to the text without changing anything breaks the existent unorderd list items:
* Test1
* Test2
* Test3
gets to
Test1 * Test2 * Test3
You can see it at the moment at

After copying the text into a texteditor it seems, that the first space charakter is somewhat else now. Deleting and replacing repairs it.
Tested with Opera v8.54 and v9
