Solution:
This seems to be caused by incompatible GTK+-schema settings, and seems to always occur, if a program uses a GTK+-library with is newer then the currently active GTK+settings, e.g. if
-
a package from unstable is used, with settings from “stable”;
this can be worked around with:
mkdir -p ~/.local/share/glib-2.0/schemas cp -pi /nix/store/...-gtk+3-3.<LATEST>/share/gsettings-schemas/gtk+3-3.*/glib-2.0/schemas/gschemas.compiled ~/.local/share/glib-2.0/schema/
-
settings are installed locally in
~/.local/share/glib-2.0/schemas
(e.g. from the workaround above), but newer packages are used, e.g. after a NixOS-upgrade or newer packages from unstable.this may be solved by:
rm -rf ~/.local/share/glib-2.0/schemas
If this does not solve the issue, the newest settings have to be copied to this directory (see workaround above)
Questions:
- Is there a way to fix this automatically?
- Or maybe to detect this, and maybe other known problems by e.g. a new program ‘nix-check’?
- Is there a place where such “solutions-to-common-problems” could be collected? Would the wiki be the right place?
