when launching thunderbird from the command line, instead of thunderbird being launched, the following message is returned: /usr/libexec/mozilla-launcher: can't find the browser :-(
Is this still an issue with 1.5? (I suppose I can always try this out tomorrow and see by myself) Firefox and Seamonkey works, so this might be fixed too, now.
Actually the problem is not in the launcher but in thunderbird's ebuild. I'll see to rebuild thunderbird later and keyword it fixed.
All fixed in tree.
