Thanks, I have exactly the same behaviour. I sent a few letters to Julien Lavergne who commited these patches and still waiting for reply.

Hello Yarema.

Just compiled 0.5.6 from git and faced with problem - when I click on Applications button panel disappear, so I need to launch it manually.
Also it crashed when I add network applet.

Volume applet doesn't shown up.

Something wrong with this commit I guess :)

Cheers,
Oleg
