Clicking 'attach file' in Compose, quits the program

[viric]

The program quits without trace.

I use gtk 3.16.6 in linux x86_64. I use the pond client bce6e0d.

Works for me. I suppose you ran into the mess that is our GTK error reporting :
#143 (comment)
There might still be something useful there though.

My fault. I had a trace (I can't tell why I didn't see it before), and it was clear about a wrong installation:

(client:15121): GLib-GIO-ERROR **: Settings schema 'org.gtk.Settings.FileChooser' is not installed

I fixed the installation and I get the dialog well.
