http://ktorrent.org/forum/viewtopic.php?t=2066 http://ktorrent.org/forum/viewtopic.php?t=2064 Crashes occur when moving up and down the file list (apparently affects only SMP systems). Reproduced by a few others using SMP systems. Upstream is aware of the problem, and its fixed in SVN738262, but isn't giving any indication when an updated stable version will be released. Untested patches are available that revert back to a (working) timers-based version of the file list generation code (http://kmlinux.fjfi.cvut.cz/~makovick/ktorrent/), but they may not provide the "proper" fix intended by the maintainer. Just downgrading to ktorrent-2.2.2 as a temporary fix. $ emerge --info Portage 2.1.3.19 (default-linux/amd64/2007.0/desktop, gcc-4.2.2, glibc-2.7-r0, 2.6.23-gentoo-r2 x86_64) ================================================================= System uname: 2.6.23-gentoo-r2 x86_64 Intel(R) Core(TM)2 CPU 6300 @ 1.86GHz Timestamp of tree: Sun, 18 Nov 2007 13:30:01 +0000 distcc 2.18.3 x86_64-pc-linux-gnu (protocols 1 and 2) (default port 3632) [enabled] ccache version 2.4 [enabled] app-shells/bash: 3.2_p17-r1 dev-java/java-config: 1.3.7, 2.1.2-r1 dev-lang/python: 2.5.1-r3 dev-util/ccache: 2.4-r7 sys-apps/baselayout: 1.12.10-r5 sys-apps/sandbox: 1.2.18.1-r2 sys-devel/autoconf: 2.13, 2.61-r1 sys-devel/automake: 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2, 1.10 sys-devel/binutils: 2.18-r1 sys-devel/gcc-config: 1.4.0-r4 sys-devel/libtool: 1.5.24 virtual/os-headers: 2.6.23-r2 ACCEPT_KEYWORDS="amd64 ~amd64" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-march=nocona -mtune=generic -O2 -pipe" CHOST="x86_64-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" CONFIG_PROTECT_MASK="/etc/env.d /etc/env.d/java/ /etc/fonts/fonts.conf /etc/gconf /etc/php/apache2-php5/ext-active/ /etc/php/cgi-php5/ext-active/ /etc/php/cli-php5/ext-active/ /etc/revdep-rebuild /etc/terminfo /etc/udev/rules.d" CXXFLAGS="-march=nocona -mtune=generic -O2 -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="ccache distcc distlocks metadata-transfer nodoc noinfo parallel-fetch sandbox sfperms strict unmerge-orphans userfetch" GENTOO_MIRRORS="http://gentoo.osuosl.org http://gentoo.netnitco.net" LANG="C" LINGUAS="en en_US" MAKEOPTS="-j4" PKGDIR="/usr/portage/packages" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --delete-after --stats --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages --filter=H_**/files/digest-*" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/portage/local/layman/xeffects /usr/local/portage" SYNC="rsync://mccoy/gentoo-portage" USE="X a52 aac acpi alsa amd64 bash-completion bitmap-fonts branding bzip2 cairo cdr cli cracklib crypt cups curl dbus dri dts dvd dvdr dvdread eds emboss evo fam ffmpeg firefox fortran gdbm gif gmp gnome gnutls gtk hal iconv imagemagick isdnlog java jpeg jpeg2k kde libnotify mad md5sum midi mikmod mmx mng motif mp3 mpeg mudflap ncurses network-cron nls nptl nptlonly nsplugin offensive ogg opengl openmp pam pcre pdf perl pertty php png ppds pppd python qt3 qt3support quicktime readline reflection scanner sdl session sndfile spl sse sse2 ssl startup-notification svg tcpd theora tiff transparency truetype truetype-fonts type1-fonts unicode vcd vim-syntax vorbis wmf x264 xcb xinerama xml xorg xscreensaver xv xvid xvmc 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" ELIBC="glibc" INPUT_DEVICES="keyboard mouse" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LINGUAS="en en_US" USERLAND="GNU" VIDEO_CARDS="nv nvidia" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LC_ALL, LDFLAGS, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS

Fixed in CVS, thanks.
