I can't confirm this bug. I just tested Thunderbird in Precise (with all updates installed) and Greybird. See the attached screenshot.
** Attachment added: "Screenshot of Thunderbird in Precise" https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/856939/+attachment/2853648/+files/thunderbird_precise.png -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to thunderbird in Ubuntu. https://bugs.launchpad.net/bugs/856939 Title: Default Thunderbird icons in Oneiric unusable with Greybird Status in “thunderbird” package in Ubuntu: Fix Released Bug description: the name says it all. i'll try to attach a screenshot to this report. the new default thunderbird icons in oeneric are just plain white and they show up very poorly, looking ugly and having very poor usability on the grey toolbar background of the xubuntu greybird theme. they probably look fine in unity, but xubuntu will have to do something about this before oeneric release. cheers, stephen.
