Bug#782446: libgtk-3-0: Segfault of GTK applications when outdated ~/.config/gtk-3.0/settings.ini is present.

[Matus Valo]

Package: libgtk-3-0
Version: 3.14.5-1
Severity: normal

Dear Maintainer,

after upgrading to debian Jessie GTK applications (evince, transmisson,
....) are segfaulting when old waldorf (Crunchbang theme) is set in ~/.config/gtk-3.0/settings.ini.

The settings.ini file contains:

[Settings] 
gtk-theme-name=waldorf
gtk-icon-theme-name=CrunchBang-Dark
gtk-font-name=Liberation Sans 10
gtk-cursor-theme-name=DMZ-White
gtk-cursor-theme-size=0
gtk-toolbar-style=GTK_TOOLBAR_ICONS
gtk-toolbar-icon-size=GTK_ICON_SIZE_SMALL_TOOLBAR
gtk-button-images=0
gtk-menu-images=1
gtk-enable-event-sounds=0
gtk-enable-input-feedback-sounds=0
gtk-xft-antialias=1
gtk-xft-hinting=1
gtk-xft-hintstyle=hintslight
gtk-xft-rgba=rgb

The application output:
