After adding a backends.xml file to my application I'm no longer able
to startup my development environment. Has anybody seen this before?
Removing the file clears everything up, but I really need to get a
backend running :-)

I don't see anything wrong with my backends.xml -->
<backends>
<backend name="thumbnailservicebatchoptimize">
<class>B2</class>
<instances>1</instances>
<options>
<dynamic>true</dynamic>
<fail-fast>true</fail-fast>
<public>true</public>
</options>
</backend>
</backends>
Thanks for any help!
