Skype icon problem with group chats

[Nicolas]

Hi,

Docky 2.2.1 bzr docky r1845 ppa running here, ubuntu 13.04 64 bits (and same problem with ubuntu 10.04 64 bits before)

Whenever someone starts a group chat with skype, there is a "1" that sticks forever on the skype icon, even after the conversation is closed / after I quit the conversation, and there is absolutely nothing I can do apart from :
- restarting docky
or
- restarting skype

Skype itself does not show any active chat / missed chat.

This bug is cumulative :
- 2 group chats => the number "2" appears on the skype icon
and so on.

It's not critical, though it's quite annoying

Thanks.
