I have tried emergeing TB with: emerge mozilla-thunderbird USE="gtk2" emerge mozilla-thunderbird USE="gtk gtk2" emerge mozilla-thunderbird and it compiled successfully. When I try to run it, however, no window ever opens. When I run 'thunderbird' from the console, I get the following output: No running windows found enigmail.js: Registering components enigmail.js: Registered components Registering Enigmail account manager extension. Enigmail account manager extension registered. /usr/bin/thunderbird: line 87: 7154 Segmentation fault $mozbin "$@" I tried removing my ~/.thunderbird directory as was proposed by a person in the forums. I then unmerged and emerged TB and the same problem occured again. The mozilla-thunderbird-0.7.3 package worked just fine for me, and was upgraded from 0.7.1, so it isn't that it was my first upgrade that caused it.

After re-emerging all of mozilla-thunderbird's dependencies (gnupg, glib, libIDL, fontconfig, jpeg, libmng, libpng, mozilla-launcher, portage, zlib, gtk+, pango, unzip, zip, expat, pkgconfig, gcc, patch, xorg-x11) and mozilla-thunderbird, it started working again. Don't know what exactly the problem was, but it has been resolved.
