#961 launch executable file options dialog doesn't work with gtk3

[j-camp]

I'm using gtk3 versions of pcmanfm and libfm built from git on Arch linux:
https://aur.archlinux.org/packages/pcmanfm-gtk3-git/
https://aur.archlinux.org/packages/libfm-gtk3-git/

I have the "Don't ask options on launch executable file" unchecked (i.e. quick_exec=0)

If I try to run an executable script by double-clicking on the file in pcmanfm, nothing happens. I expected to see a dialog asking if I want to open or execute the file.

Attached is a backtrace.

Similar with #960.
With changing gtk_builder_add_from_file() returning GError, it shows

2行目に無効なプロパティ: GtkDialog.has_separator

(the above if Japanese)

Would you try the attached patch?
