Preferred applications ignored in LXDE

[Lars Nooden]

I installed xxxterm and now when I click on links in Sylpheed (and other 
apps) it gets called up instead of Chromium-browser.  I have set Chromium 
as the preferred application in LXDE Menu->Preferences->Preferred 
Applications, yet these settings are ignored. 

Is there another place to set the preferred browser, or is this a bug?
