The ubuntu deb build applies this patch and some related ones that make the theme monochrome:

In Oneiric (and Precise) some of the coloured Icons were replaced by black&white pictograms, but not consistently all. For example the Lightning Icons still remain coloured, as they were before. I don't know why some Icons were replaced by pictograms (is this because of a new GTK-Theme?) , this is only in the Linux version of TB, the Windows version still has the coloured icons. It would have been better if the old standard theme remains untouched, and a new theme would have been created for the new black&white pictograms. See attached screenshot for the weird icons. Possible work-around: Download Thunderbird from mozilla, extract a file called omni.ja and overwrite the copy at /usr/lib/thunderbird/. Not sure if this has undesired effects (it may delete all your email, so be careful!), but it works for me.
