Update check for spell checker extension doesn't seem to work

[Bernhard Baier]

Hello,

it seems that the check for update-mechanism doesn't seem to work for 
the following spell checker:
http://extensions.libreoffice.org/extension-center/uppsersorbian-spell-checker

I have locally installed version 2.02.05, version 2.02.06 is the (only) 
version which is online. when I try to check for updates in the 
extension manager it says that there is no update available.
In the description.xml stands either
<version value="2.02.05" />
or
<version value="2.02.06" />

Any hint?

thank you & best regards
Bernhard
