after installing the firefox-beta i noticed strange behaviour in thunderbird: only the last attachment of a mail seems to evaluated and displayed inline if it's plain text. so signed mails don't have a body and attachments get "lost" however they are still there, as thunderbird-bin can access them Reproducible: Always Portage 2.1.5_rc3 (default-linux/x86/2007.0, gcc-4.3.0, glibc-2.7-r2, 2.6.24-thinkpad-r4 i686) ================================================================= System uname: 2.6.24-thinkpad-r4 i686 Intel(R) Core(TM)2 CPU T7200 @ 2.00GHz Timestamp of tree: Tue, 15 Apr 2008 10:15:02 +0000 ccache version 2.4 [enabled] app-shells/bash: 3.2_p33 dev-java/java-config: 1.3.7, 2.1.5 dev-lang/python: 2.5.1-r5 dev-util/ccache: 2.4-r7 sys-apps/baselayout: 2.0.0 sys-apps/sandbox: 1.2.18.1-r2 sys-devel/autoconf: 2.13, 2.62 sys-devel/automake: 1.5, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2, 1.10.1 sys-devel/binutils: 2.18-r1 sys-devel/gcc-config: 1.4.0-r4 sys-devel/libtool: 1.5.26 virtual/os-headers: 2.6.24 ACCEPT_KEYWORDS="x86 ~x86" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -march=core2 -pipe -fomit-frame-pointer -mfpmath=sse -mssse3" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/3.5/env /usr/kde/3.5/share/config /usr/kde/3.5/shutdown /usr/share/config /var/lib/hsqldb" CONFIG_PROTECT_MASK="/etc/env.d /etc/env.d/java/ /etc/fonts/fonts.conf /etc/gconf /etc/gentoo-release /etc/php/apache2-php5/ext-active/ /etc/php/cgi-php5/ext-active/ /etc/php/cli-php5/ext-active/ /etc/revdep-rebuild /etc/terminfo /etc/texmf/web2c /etc/udev/rules.d" CXXFLAGS="-O2 -march=core2 -pipe -fomit-frame-pointer -mfpmath=sse -mssse3" DISTDIR="/usr/portage/distfiles" FEATURES="ccache distlocks metadata-transfer parallel-fetch sandbox sfperms strict unmerge-orphans userfetch" GENTOO_MIRRORS="http://mirrors.sec.informatik.tu-darmstadt.de/gentoo/ ftp://sunsite.informatik.rwth-aachen.de/pub/Linux/gentoo" LDFLAGS="" LINGUAS="de" MAKEOPTS="-j4" PKGDIR="/usr/portage/packages" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --stats --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/portage/local/layman/sunrise /usr/portage/local/layman/jokey /usr/portage/local/layman/x11 /usr/local/portage" SYNC="rsync://rsync1.de.gentoo.org/gentoo-portage" USE="X X509 aalib acl acpi alsa amazon apache2 audiofile bash-completion berkdb bluetooth bzip2 cairo cardbus cdda cddb cdinstall cdio cdparanoia cdr cli cracklib crypt css ctype cups curl dbus device-mapper divx dri dvd dvdr dvdread encode fat fftw firefox flac foomaticdb fortran games gd gdbm geldkarte gif gimp gimpprint gmedia gnuplot gnutls gpg gpgme gphoto2 gpm graphviz gtk hal hbci hdaps hibernate-script hou iconv icq id3 id3tag imap imlib imlib2 innodb ipod ipv6 ipw3945 irc jabber java java5 java6 javascript jpeg jpeg2k kde lame laptop latex logrotate metric midi mikmod mime mmap mmx mmxext mp2 mp3 mp4 mpeg mpeg2 mplayer msn mudflap mysql mysqli ncurses network networkmanager nfs nls nowin nptl nptlonly nsplugin ntfs obex offensive ogg openct opengl openmp pam pcmcia pcre pcsc-lite pdf perl php png pop postgres ppds python qt3 qt3support qt4 query-browser rar rdesktop readline real realmedia reflection reiser4 reiserfs replytolist samba science sco_flowcontrol sdl session smartcard smime smp smtp sou sound spell spl sse sse2 ssl ssse3 subversion svg symlink tcpd theora threads tidy tiff truetype twolame unicode usb userlocales vamp vcd videos vim-syntax vim-with-x vlm vnc vorbis webdav wifi win32codecs wmf wmp x264 x86 xcomposite xinerama xml xorg xosd xpm xprint xscreensaver xvid zeroconf zip zlib" ALSA_CARDS="hda-intel" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mulaw multi null plug rate route share shm softvol" APACHE2_MODULES="actions alias auth_basic authn_alias authn_anon authn_dbm authn_default authn_file authz_dbm authz_default authz_groupfile authz_host authz_owner authz_user autoindex cache dav dav_fs dav_lock deflate dir disk_cache env expires ext_filter file_cache filter headers include info log_config logio mem_cache mime mime_magic negotiation rewrite setenvif speling status unique_id userdir usertrack vhost_alias" ELIBC="glibc" INPUT_DEVICES="mouse keyboard" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LINGUAS="de" USERLAND="GNU" VIDEO_CARDS="ati radeon vesa" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LANG, LC_ALL, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS
I had this problem when I tested gcc-4.3, so this may not be caused by firefox-3.0_beta5: running it now and thunderbird both compiled with gcc-4.2 and thunderbird works fine. See also: https://bugzilla.mozilla.org/show_bug.cgi?id=426228
indeed looks like the very same bug.
