Hello folks,

according to
http://community.skype.com/t5/Windows-desktop-client/Skype-is-opening-a-Browser-s-tab-Window-each-time/td-p/3573947

http://community.skype.com/t5/Windows-archive/The-New-Banner-Ad-s-Above-People-s-Profiles/m-p/2971118#M239490

https://apps.skype.com/chatadwidget/ has the purpose to annoy the user with ads
in the chat window.

Garbage from that site is supposed to be embedded every time unless one takes
further action (buying credit, using old Skype version or simply hack it).

The external browser opening is the result of Wine's 'urlmon' handling when the
client returns 'INET_E_DEFAULT_ACTION' during protocol binding.

'BindProtocol_StartEx' calls client's 'IInternetProtocol::Start'

The client returns 0x800c0011 -> 'INET_E_DEFAULT_ACTION' (expected) which Wine
handles differently than native 'urlmon'.
It stops binding and defers further action to default registry protocol
association which in turns creates an own browser process (or reuses existing
native browser).

Likely the same issue as bug 24285 or other bugs with applications that make
use of embedded browser control but get external browser processes via default
registry assoc handler.

'winetricks -q ie8' works around but only 'urlmon' and its link dependencies
are really needed here.
