[Bug 400036] Re: package mozilla-plugin-gnash 0.8.5-0ubuntu1 failed to install/upgrade:

[Boger]

The same thing happened to me, I've found thread http://ubuntuforums.org/archive/index.php/t-1075776.html
And problem looks similar 
/etc/alternatives/iceape-flashplugin and /var/lib/dpkg/alternatives/iceape-flashplugin are missing. 
I've created them by hands and 


But after runing sudo apt-get install  -f gnash, this files gone.
