If executed in a pure environment (nix-shell --pure) or depending on the
`gtk3` version of the system Signal-Desktop was e.g. crashing when
clicking on a PDF attachment (instead of showing the dialog to save a
file).
Using wrapGAppsHook and setting XDG_DATA_DIRS to the correct version
fixes this bug.
The error message was the following:
```
(signal-desktop:30756): Gtk-WARNING **: 14:04:49.073: Could not find the icon 'user-home-symbolic-ltr'. The 'hicolor' theme
was not found either, perhaps you need to install it.

Trace/breakpoint trap
```
Nixpkgs is a collection of packages for the Nix package manager. It is periodically built and tested by the Hydra build daemon as so-called channels. To get channel information via git, add nixpkgs-channels as a remote:
% git remote add channels git://github.com/NixOS/nixpkgs-channels.git
For stability and maximum binary package support, it is recommended to maintain
custom changes on top of one of the channels, e.g. nixos-18.03 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-18.03
For pull-requests, please rebase onto nixpkgs master.
NixOS Linux distribution source code is located inside
nixos/ folder.
