[win64] GTK file picker crashes on choose

[Liam P. White]

Removing/commenting out these lines in the Inkscape source file "src/file.cpp" fixes it:

551: delete openDialogInstance;
561: delete openDialogInstance;

900: delete saveDialog;
911: delete saveDialog;

1298: delete importDialogInstance;
1309: delete importDialogInstance;

Confirmed on WIndows 8.1, Inkscape 0.91 (64bit, 7zip package).

Still affecting win64 users (I can't test for now)?

Crash with GTK+ dialogs not reproduced with Inkscape 0.92.0 r15299 (64bit, MSI) on Windows 10: renders preview of selected image (tested with SVG, PNG, GIF, BMP, TIF, JPG) and loads selected file ok.

crash reproduced on Windows 10, Inkscape 0.92+devel 15423

if I use the GTK dialog to open a file, I get the attached popup error message, followed by this DOS output

C:\Users\penne_000\AppData\Roaming\InkscapeBZR\build\inkscape>inkscape

(inkscape.exe:1080): Gtk-WARNING **: Could not find the icon 'object-visible-ltr'. The 'hicolor' theme
was not found either, perhaps you need to install it.
You can get a copy from:
        http://icon-theme.freedesktop.org/releases

(inkscape.exe:1080): GLib-GIO-ERROR **: No GSettings schemas are installed on the system

Emergency save activated!
Emergency save completed. Inkscape will close now.
If you can reproduce this crash, please file a bug at www.inkscape.org
with a detailed description of the steps leading to the crash, so we can fix it.

Gtk-Message (recursed): GtkDialog mapped without a transient parent. This is discouraged.

This is likely a packaging issue with GTK3 on Windows (Inkscape trunk uses GTK3, on all platforms), and probably best tracked separately.

Proposing to close as 'Fix Released' with milestone 0.92.0 - it works as expected with Inkscape 0.92.0 r15299 (64bit, MSI) (tested on Windows 10, see comment 4).

The crash with trunk (GTK3) mentioned in comments 5-8 (likely due to missing - i.e. not installed (devlibs), or not found at runtime (env) - glib schemas) has been filed separately as
* Bug #1663884 “crash when attempting to use gtk open dialog in Inkscape trunk, 64 bit, Windows 10”
