Bwinton, Andreas, any idea where do these icons come from? I could not see them in the format-buttons.png of gnomestripe theme. But i qute (windows) the icons for indentation are in that file. Do they come from the system (gnome) theme on linux?
Could this be a Linux icon theme problem I'm not seeing wizh my Linux icon theme? This icons are coming from GTK http://hg.mozilla.org/comm-central/file/e622ef230d64/mail/themes/gnomestripe/mail/compose/messengercompose.css#l398 and http://hg.mozilla.org/comm-central/file/e622ef230d64/mail/themes/gnomestripe/mail/compose/messengercompose.css#l405
Anthony, do you still see this behavior?

Created attachment 651499 [details] [diff] [review] patch Anthony, you're right. I have now a totally unpatched Ubuntu 12.04 and can see your problem. My old Ubuntu always showed the icons correct with gtk-unindent-ltr and gtk-unindent-rtl. Now with unindent and intent it works on both Ubuntus. Andreas, I hope you have a non-Ubuntu system to check if the icons are still working.
I didn't see any regressions on Fedora 17 (also GTK+ 3.4), so we should be good. Going to look into the deeper cause a bit, but it works for us regardless it seems.
Comment on attachment 651499 [details] [diff] [review] patch Also worked well when I tried the Force RTL, so I think we're good.
Verified fixed with Thunderbird 17.0a1 2012-08-21.
