Crash saving masked link containing image if Layers and Objects dialog open

Steps to reproduce:

  • open Inkscape
  • open layers and objects dialog (Ctrl+Shift+L)
  • open test_2.svg
    • basic file structure:
<svg>
<defs><mask><circle/></mask></defs>
<a mask>
 <image>
</a>
</svg>
  • save as pdf

    Better fix for https://gitlab.com/inkscape/inkscape/-/issues/158 without g_return_if_fail
    
    Don't use `g_return_if_fail` for a valid case, it depends on
    `G_DISABLE_CHECKS` and is for preconditions (programmer error).
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
