Sometimes mozilla-thunderbird freezes when composing a new message (e.g. create a new message or reply to a message). If launched from a terminal, I find the following error message: $ thunderbird No running windows found (thunderbird-bin:19278): Gdk-WARNING **: gdk_property_get(): length value has wrapped in calculation (did you pass G_MAXLONG?) [THE FOLLOWING APPEARS ONCE I KILL THE APP] *** glibc detected *** free(): invalid pointer: 0xbfe0b48c *** /usr/libexec/mozilla-launcher: line 116: 19278 Killed "$mozbin" "$@" thunderbird-bin exited with non-zero status (137) I've tried with different versions of mozilla-thunderbird and mozilla-launcher (latest stable and latest unstable) but I always eventually have this problem. Note that it seems too happen erratically, ie I can compose N new messages and suddenly the (N+1)th message will cause the application to freeze. # emerge info Portage 2.0.53 (default-linux/x86/2005.1, gcc-3.4.4, glibc-2.3.5-r2, 2.6.14-gentoo-r5 i686) ================================================================= System uname: 2.6.14-gentoo-r5 i686 AMD Athlon(tm) XP 2600+ Gentoo Base System version 1.6.13 dev-lang/python: 2.3.5-r2, 2.4.2 sys-apps/sandbox: 1.2.12 sys-devel/autoconf: 2.13, 2.59-r6 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r1 sys-devel/binutils: 2.16.1 sys-devel/libtool: 1.4.3-r4, 1.5.20 virtual/os-headers: 2.6.11-r2 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CBUILD="i686-pc-linux-gnu" CFLAGS="-march=athlon-xp -Os -pipe -mmmx -msse -m3dnow" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3/share/config /usr/lib/X11/xkb /usr/share/config /usr/share/texmf/dvipdfm/config/ /usr/share/texmf/dvips/config/ /usr/share/texmf/tex/generic/config/ /usr/share/texmf/tex/platex/config/ /usr/share/texmf/xdvi/ /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-march=athlon-xp -Os -pipe -mmmx -msse -m3dnow" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig distlocks sandbox sfperms strict" GENTOO_MIRRORS="http://www.mirrorservice.org/sites/www.ibiblio.org/gentoo" LANG="en_GB.UTF-8" LC_ALL="en_GB.UTF-8" LINGUAS="en fr" MAKEOPTS="-j2" PKGDIR="/mnt/cdrom" PORTAGE_TMPDIR="/usr/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.europe.gentoo.org/gentoo-portage" USE="x86 3dnow X acpi alsa avi bindist bzip2 cdr crypt cups dvd esd exif f77 foomaticdb fortran gif gnome gpm gtk gtk2 imap java jpeg mbox mmx mp3 mpeg ncurses nls nsplugin nvidia oggvorbis opengl oss pam pdflib perl png ppds python readline spell sse ssl tcpd tiff truetype unicode vorbis win32codecs wmf xml xml2 xmms xprint zlib linguas_en linguas_fr userland_GNU kernel_linux elibc_glibc" Unset: ASFLAGS, CTARGET, LDFLAGS I've described my problems in the forums but I think there is a bug somewhere, see http://forums.gentoo.org/viewtopic-t-410917.html
Reopen with some debugging info if you still have problems with current versions. http://www.gentoo.org/doc/en/bugzilla-howto.xml http://www.gentoo.org/proj/en/qa/backtraces.xml Thanks.
In my case its just a signature which turned to a 4 Mb + size from the original 2kb. I was stocked in this for 2 days. What a slow analysis I have. :(
