Please describe the problem more accurately. Attaching your ~/.config/audacious/config file may be an idea, too.

Audacious is unrelated to KDE.

> with version in updates

It only includes minor changes.

cat ~/.config/audacious/config 
[gtkui]
column_widths=-1,-1,-1,-1,-1
column_expand=1,1,1,0,0
player_x=230
player_y=225

[audgui]
filesel_path=/home/sergio/Documents/MyMusic/grupos

[gtkui-layout]
item_count=0

before report this bug I clean all file in ~/.config/audacious/ except playlists 

In the Navigation bar, in first row of opened dialog , we can see the folders hierarchically, but when I click on them nothing happened. 
I switch to gnome and works in there , so just happens in KDE, I test it in two different computers . 

Thanks

Better. Thanks!

Confirmed. It's specific to KDE (dunno which component to choose in bugzilla), but not specific to Audacious.

For example, the Eye of GNOME image viewer (eog) is affected, too.

In KDE, when clicking the various folder buttons for the current path as displayed in the following image ( https://developer.gnome.org/gtk3/3.2/GtkFileChooserDialog.html ) nothing happens.

yeap , eog is also affected by this bug ... 

Thanks ! ,

are these each gtk3 apps?

What versions of oxygen-gtk are you using?

rpm -q oxygen-gtk2 oxygen-gtk3

I think I can reproduce the problem on my box with 
oxygen-gtk-1.3.2-1.fc20.x86_64

in audacious Open Files dialog, clicking on path icon items at the top does nothing.

Hrm, switching to Adwaita, it does the same thing.  maybe not related to oxygen-gtk afterall, more testing...

ok, wierd, restart app, and now it works in Adwaita (I blame gremlins)

what is "in Adwaita" ?

I tested Adwaita gtk theme, and at first clicking icons there had the same problem as oxygen-gtk.  but it fixed itself restarting the app after change of theme.

Temporary fix is set "Drag windows from titlebar only" in oxygen-settings.

I can confirm 

command oxygen-settings -> widget style -> general -> windows drag mode -> "Drag windows from titlebar only"

fix it.

Please test oxygen-gtk3-1.3.3-2.fc20 from updates-testing with "Drag windows from all empty areas" in oxygen-settings.
