[Fedora23] audacity hang when startup

I found the solution:
Gnome2 accessibility is enabled and this requires libgail-gnome which is not available anymore :frowning:
This occurs even if audacity is compiled with wxGTK3.

To disable gnome2 accessibility, use the command:

gconftool-2 --set /desktop/gnome/interface/accessibility --type bool false

After that, audacity starts properly again :smiley:
