bug#16809: 24.3; When starting Emacs 24.3.1 in Xubuntu 13.10, "Theme parsing error: gtk-widgets.css" is always output to console |
|
Date: |
Wed, 19 Feb 2014 16:38:45 +0200 |
I have just updated my Xubuntu to version 13.10, and installed all the latest
package upgrades. To make sure that this problem didn't result from some funky
package conflict issue, I removed all emacs-related packages and files, then
reinstalled emacs24 via the Ubuntu software center (which gets me Emacs
v24.3.1). The X version is 1.14.5.
The problem: each time I start Emacs from the command line, it outputs a
warning. For example:
teemu@teemu-desktop:~ $ emacs &
[2] 11450
teemu@teemu-desktop:~ $
(emacs:11450): Gtk-WARNING **: Theme parsing error:
gtk-widgets.css:3274:48: Expected ',' in color definition
I tried commenting out all color-setting commands and the font-setting command
from my init.el file, but that didn't help. I also tried starting without
customizations:
teemu@teemu-desktop:~ $ emacs -Q &
[4] 11727
teemu@teemu-desktop:~ $
(emacs:11727): Gtk-WARNING **: Theme parsing error:
gtk-widgets.css:3274:48: Expected ',' in color definition
but obviously that didn't help.
The number reported at the beginning of the warning line, after "emacs:",
changes from one execution to another; so, far I've got at least these:
11450, 11531, 11548, 11590, 11605, 11618, 11639, and 11649.
What follows is (a) the contents of my init.el file, (b) the contents of
/usr/share/emacs/24.3/site-lisp/debian-startup, (c) the contents of file
/home/teemu/.emacs.d/elpa/ruby-mode-1.1/ruby-mode, (d) the packages
installed on my machines whose
name includes gtk, and (e) the text generated by executing the
function report-emacs-bug.
