** Changed in: gnome-shell (Ubuntu) Status: Incomplete => Won't Fix

The CSS engine seems to be trying to resolve these relative paths with respect to the user's home directory, instead of relative to the path of the included CSS file where the the "url(...)" declaration exists (per sec 6.4 of the w3c REC-CSS1 specification: http://www.w3.org/TR/REC-CSS1/#url ). NOTE: as far as I can tell, the theme still *looks* correct, suggesting that perhaps the CSS engine is in fact finding these resources in the correct paths, *after* logging these errors? This bug did not exist in the previous version I upgraded from: Gnome Shell v3.4.1 I discovered this bug because I use a "custom" theme which includes the gnome-shell.css file from default theme and then overrides a few select properties -- as mentioned, this worked fine with Gnome Shell v3.4.1. Steps to reproduce: 1) Install Ubuntu-Gnome 15.04 containing Gnome Shell 3.14.4 $ lsb_release -rd Description: Ubuntu 15.04 Release: 15.04 $ uname -a Linux tray 3.19.0-16-generic #16-Ubuntu SMP Thu Apr 30 16:09:58 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux $ gnome-shell --version GNOME Shell 3.14.4 $ apt-cache policy gnome-shell gnome-shell: Installed: 3.14.4-0ubuntu1 Candidate: 3.14.4-0ubuntu1 Version table: *** 3.14.4-0ubuntu1 0 500 http://us.archive.ubuntu.com/ubuntu/ vivid/universe amd64 Packages 100 /var/lib/dpkg/status 2) create a new user named "gnomeshellbug" and login as that user 3) create the following .themes directory for the gnomeshellbug user... $ find /home/gnomeshellbug/.themes/ /home/gnomeshellbug/.themes/ /home/gnomeshellbug/.themes/BuggyCssImportShellTheme /home/gnomeshellbug/.themes/BuggyCssImportShellTheme/gnome-shell /home/gnomeshellbug/.themes/BuggyCssImportShellTheme/gnome-shell/gnome-shell.css $ cat /home/gnomeshellbug/.themes/BuggyCssImportShellTheme/gnome-shell/gnome-shell.css @import url("/usr/share/gnome-shell/theme/gnome-shell.css"); .panel-button { /* not so much damn padding */ -natural-hpadding: 6px; -minimum-hpadding: 4px; } 4) Note that the imported file /usr/share/gnome-shell/theme/gnome- shell.css mentioned above contains url refrences to files which exist in the same /usr/share/gnome-shell/theme/ directory... $ grep message-tray-background.png /usr/share/gnome-shell/theme/gnome-shell.css background: #2e3436 url(message-tray-background.png); $ ls -l /usr/share/gnome-shell/theme/message-tray-background.png -rw-r--r-- 1 root root 19246 Mar 23 16:13 /usr/share/gnome-shell/theme/message-tray-background.png 5) Use the tweak-tool to enable the "User Themes" extension 6) Use the tweak-tool to select BuggyCssImportShellTheme as the Shell theme 7) observe log messages like these in syslog....
