Some apps are showing the incorrect icon in the applications menu. After a lot of debugging, I figured out icons with an extension will always be replaced by an icon found after it.

In my case, Thunderbird was getting the icon from my icon theme, rather than the package one which was found first.

It was caused by checking for the filename *with* extension as the key, rather than without which is how they're stored.

Repo has xpra packages for 17.04, but not winswitch.

xpra-0.8.0-9.fc18.x86_64
winswitch-0.12.18-2.x86_64
