FYI, since updating to webkitgtk-2.32.0 (commit 3c5e1412e3ef769df8e4826d0aedabaa3aa0d631), epiphany fails to launch: no window appears, although GNOME Shell shows an empty outline in overview mode, as if there's a window but it has never been painted.
When running 'epiphany' from the command line, I see the followin warning from 'bwrap', which indicates that it's looking in /usr/bin: --8<---------------cut here---------------start------------->8--- mhw@jojen ~$ epiphany ** (epiphany:1016): WARNING **: 18:36:48.495: Registering special URI scheme ftp is no longer allowed bwrap: Can't find source path /usr/bin: No such file or directory --8<---------------cut here---------------end--------------->8--- I wonder if this only works when Guix is run on top of a more traditional OS that has /usr/bin. Is anyone successfully able to use Epiphany on a pure Guix system (without /usr/bin) with Webkitgtk-2.32.0? (The Webkitgtk version is shown in the "About Web" window, which is accessible from the hamburger menu. Mark
