[gentoo-user] Firefox-bin-28.0-r1: Missing commonDialog icons? Anybody else seeing this?

[Urs Schutz]

Hello

When starting up firefox-bin this morning I got the
following dialog box popping up:

$ firefox-bin
"Configuration Error"
"Failed to read configuration file. Please contact your
system administrator."

After confirming with "OK" the firefox-bin process is
terminated. No browser today for me :-(

$ firefox-bin -version
Mozilla Firefox 28.0

What I tried to do, without success:

uninstalled and re-installed firefox-bin, cleaned the
program directory and my configuration in between

checked to run firefox-bin as root

Checked whether there is a file named mozilla.cfg, there is
none.

created empty /opt/firefox/defaults/pref/mozilla.cfg
added "//" to the first line of mozilla.cfg

Safe mode pops up the same dialog box:
$  firefox-bin -safe-mode

Started the profile browser:
$  firefox-bin -P
The profile browser lets me delete and create profiles. But
firefox still shows the dialog and quits.

checked bugs (had to install chrome, but didn't like
chrome): 
https://bugzilla.mozilla.org/show_bug.cgi?id=672671
https://bugzilla.mozilla.org/show_bug.cgi?id=833117

Checked with strace which files cannot be read:
Just when the dialog box pops up I see:
urs@Evo ~ $ strace -e trace=file -f firefox-bin
<<snipped a lot of content here...>>
access("/opt/firefox/browser/chrome", F_OK) = 0
access("commonDialog.png", R_OK) = -1 ENOENT (No such file
or directory)

R_OK) = -1 ENOENT (No such file or directory)
access("/opt/firefox/browser/chrome/icons/default/commonDialog16.xpm",
R_OK) = -1 ENOENT (No such file or directory)

This icons are really missing in my installation:
urs@Evo ~ $ ls /opt/firefox/browser/chrome/icons/default/
default16.png  default32.png  default48.png

I downgraded firefox-bin to the latest stable version 24.4.0
The icons from above are still not installed, but this
version is starting up and is usable. So for me there is a
workaround. I am still a little nervous about security
concerns with an old browser version.

Additional information here, some lines of the Gentoo
emerge log history: 
urs@Evo ~ $ genlop firefox-bin
Thu Mar  6 21:57:34 2014 >>> www-client/firefox-bin-27.0.1
Thu Mar 20 08:42:44 2014 >>> www-client/firefox-bin-28.0
Sat Mar 29 08:47:39 2014 >>> www-client/firefox-bin-28.0-r1

I am pretty sure that I had used firefox-bin-28.0 last week
without troubles. So, is this just firefox-bin-28.0-r1?
Anybody else seeing this?

Thanks
Urs
