A last word (yes I know, I should have made tried to post only one comment with all this), to solve the problem I had 2 solutions:
1) In Thunderbird menu: Edit/Prefrences/Display/Fonts, uncheck "allow to use other fonts" -> the catch is that all emails will use your default fonts. 2) uninstall MS fonts (K menu/system parameters/system administration/Font installer) I've chosen the second option, since I believe that the fonts might not have a totaly compatible format... -- Thunderbird crashes with segfault https://launchpad.net/bugs/54663 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
