When I launch a GUI application, such as 'mousepad' or 'thunar' from a
console, I get a warning:
$ pkexec thunar
(thunar:14366): Gtk-WARNING **: 16:25:21.434: Theme parsing error:
gtk-contained-dark.css:2871:228: Missing closing bracket for :not()
$ mousepad
(mousepad:14624): Gtk-WARNING **: 16:45:35.868: Theme parsing
error: gtk-contained-dark.css:2871:228: Missing closing bracket for :not()
$ thunar
Notice, when I start 'thunar' as a normal user I don't get this warning,
but when I launch 'mousepad' as a normal user I do get this warning.
Warning message is descriptive enough, so I've tried to find this
'gtk-contained-dark.css' file and fix it by myself:
# find / -name "gtk-contained-dark.css"
find: ‘/var/lib/lxcfs/cgroup’: Input/output error
/usr/share/themes/Bluebird/gtk-3.0/gtk-contained-dark.css
#
I don't use "Bluebird" theme, so I've decided to simply uninstall
'bluebird-gtk-theme' package, but it didn't helped.
Now, when I try to find 'gtk-contained-dark.css' file, it looks like I
don't any files with that name:
# find / -name "gtk-contained-dark.css"
find: ‘/var/lib/lxcfs/cgroup’: Input/output error
#
And there are no other packages exist that could provide a file with
this name:
$ apt-file find gtk-contained-dark.css
bluebird-gtk-theme:
/usr/share/themes/Bluebird/gtk-3.0/gtk-contained-dark.css
$
Yet, the same warning message still being displayed every time.
I suspect there is some caching mechanism within GTK, that could cause
this problem, but I can't find any information about that.
Can someone help me to resolve this mystery?
My system info:
