No icons display in Inkscape, causes crash on opening dialogs

[rileyinman]

Describe the bug
After installing inkscape either in the user or system profile, no icons are found. When opening dialogs such as "Fill and stroke" or "Layers" the program crashes. I've confirmed this on two of my machines.

To Reproduce
Steps to reproduce the behavior:

1. nix-shell -p inkscape
2. Run inkscape
3. Note that all icons display incorrectly
4. Navigate to Object -> Fill and Stroke
5. Observe crash

Expected behavior
Inkscape should have the full set of icons and dialogs should be accessible.

I think you can easily fix this issue by installing an icon theme to your system.

I believe these icons are part of Inkscape. Possibly issue with gdk-pixbuf loaders – though, I cannot reproduce it within plain xterm session.

What desktop environment are you running? Does adding wrapGAppsHook to Inkscape’s nativeBuildInputs help?

[rileyinman]

@jtojnar Sorry, I should have mentioned - I already tried the following overlay for inkscape

self: super:
{
  inkscape = super.inkscape.overrideAttrs(old: rec {
    nativeBuildInputs = old.nativeBuildInputs ++ [ super.wrapGAppsHook ];
    buildInputs = old.buildInputs ++ [ super.gdk_pixbuf ];
  });
}

after reading the gdk-pixbuf issue and related ones. Unfortunately it didn't seem to change anything after rebuilding and compiling.

One of my computers is running sway (launched via startx) and the other i3 + sddm.

Maybe wrapGAppsHook does not work because of strictDeps:

nixpkgs/pkgs/applications/graphics/inkscape/default.nix

Line 25 in 8d1510a

strictDeps = true;

[rileyinman]

@symphorien That worked! I added strictDeps = false to the overlay and all the icons show up, and dialogs work. I tried looking up docs on strictDeps but I couldn't find much about it, what does it do exactly?

[worldofpeace]

😕 I thought the issue with strictDeps only touched gobject-introspection

• setup hook of gobject-introspection in nativeBuildInputs does not run with strictDeps #56943

[jtojnar]

IIRC, it might also affect hook’s deps not being picked up correctly. Does the following work with strictDeps enabled?

self: super:
{
  inkscape = super.inkscape.overrideAttrs(old: rec {
    nativeBuildInputs = old.nativeBuildInputs ++ [ super.wrapGAppsHook ];
    buildInputs = old.buildInputs ++ [ super.gdk_pixbuf super.librsvg ];
  });
}

[rileyinman]

@jtojnar Yes, that worked! Would the best workaround for now be to add those inputs to the derivation?
