a good backtrace would be most useful, see [1] [1] http://www.gentoo.org/proj/en/qa/backtraces.xml
Hmm, I have all system without -gdb flag. And it would take quite long to rebuild all. Is there some way to build just the one application?
emerge -1 <package> Please do read that link Gilles posted as adding -g to CFLAGS isn't enough by itself. Thanks

Hum, that's not good, all thos "(no debugging symbols found)" should disappear. You will probably need to rebuild glib, gtk, glibmm, gtkmm, gconf, libsigc++ and other deps you enabled via use flags to get a better backtrace.
uff, it look like it have some debug flag: # emerge -1av app-misc/workrave These are the packages that would be merged, in order: Calculating dependencies... done! [ebuild R ] app-misc/workrave-1.9.0 USE="dbus nls xml -arts -debug -distribution -gnome -kde" 0 kB wouldn't be enough to compile it with debug use flag?
no, USE="debug" is not enough, please read the documentation, you need symbols per used libs, CFLAGS="${CFLAGS} -g", FEATURES="$FEATURES splitdebug" otherwise your debugger won't be able to do its job.
so I will add to FEATURES splitdebug my /etc/make.conf # These settings were set by the catalyst build script that automatically built this stage # Please consult /etc/make.conf.example for a more detailed example CHOST="i686-pc-linux-gnu" #CFLAGS="-march=pentium-m -O2 -pipe -fomit-frame-pointer" CFLAGS="-march=pentium-m -O2 -ggdb" CXXFLAGS="${CFLAGS}" INPUT_DEVICES="keyboard mouse synaptics" VIDEO_CARDS="intel" #"i810 i915" USE="slang unicode -gnome -arts kde nsplugin java alsa dri nls xv qt truetype dvd xvid sdl opengl dvdread jack nptl nptlonly 7zip bluetooth faad" GENTOO_MIRRORS="rsync://192.168.1.1/gentoo-portage/distfiles rsync://192.168.1.1/gentoo-portage/ rsync://ftp6.linux.cz/pub/linux/gentoo/ rsync://ftp.fi.muni.cz/pub/linux/gentoo/ ftp://ftp.wh2.tu-dresden.de/pub/mirrors/gentoo ftp://ftp.tu-clausthal.de/pub/linux/gentoo" #SYNC="rsync://192.168.1.1/gentoo-portage" PORTDIR_OVERLAY="/usr/local/portage" PORTDIR="/mnt/nfs_portage" DISTDIR="${PORTDIR}/distfiles" PKGDIR="${PORTDIR}/packages" RPMDIR="${PORTDIR}/rpm" FEATURES="-userfetch distlocks" #ALSA_CARDS="intel8x0" ALSA_CARDS="hda-intel" LINGUAS="cs us"
