this problem is hard to explain but whenever i try to use kwirelessmonitor it simply will freeze up without warning and will later open the kde crash handler.i can't tell what triggers this problem.i apologize for bad information and being undescriptive in the reproduction steps but this all happens at random. Reproducible: Sometimes Steps to Reproduce: 1.run kwirelessmonitor 2. try checking wireless statistics at various times 3. the program will freeze up at random Actual Results: the program becomes unresponsive and will sometimes later bring up the kde crash handler. Expected Results: statistics about my wireless network should be displayed Portage 2.0.51.22-r2 (default-linux/x86/2005.0, gcc-3.3.5-20050130, glibc-2.3.5- r1, 2.6.12-gentoo-r9 i686) ================================================================= System uname: 2.6.12-gentoo-r9 i686 Celeron (Coppermine) Gentoo Base System version 1.6.13 ccache version 2.3 [enabled] dev-lang/python: 2.3.5 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 sys-devel/binutils: 2.15.92.0.2-r10 sys-devel/libtool: 1.5.18-r1 virtual/os-headers: 2.6.11-r2 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -march=pentium3 -fomit-frame-pointer -pipe" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3/share/config /usr/share/ config /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/env.d" CXXFLAGS="-O2 -march=pentium3 -fomit-frame-pointer -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig ccache distlocks nostrip sandbox sfperms strict userpriv us ersandbox" GENTOO_MIRRORS="http://distfiles.gentoo.org http://distro.ibiblio.org/pub/Linux/ distributions/gentoo" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="x86 X aac alsa apm arts avi berkdb bitmap-fonts browserplugin cdr clamav cr ypt cups curl debug dga divx4linux doc eds emboss encode esd fam ffmpeg foomatic db fortran gd gdbm gif gnome gpm gstreamer gtk gtk2 guile imlib ipv6 java jpeg k de libg++ libwww mad mikmod motif mozilla mp3 mpeg mysql ncurses nls ogg oggvorb is opengl oss pam pdflib perl png python qt quicktime readline sdl spell sse sse 2 ssl svga tcpd tiff truetype truetype-fonts type1-fonts v4l v4l2 vorbis win32co decs xml2 xmms xv xvid zlib video_cards_i810 userland_GNU kernel_linux elibc_gli bc" Unset: ASFLAGS, CTARGET, LANG, LC_ALL, LDFLAGS, LINGUAS, MAKEOPTS, PORTDIR_OVER LAY

please try upgrading to kdelibs-3.4.2-r1, kde-env-r4, and rebooting the machine. please close the bug if this fixes the problem.
just tried that but no change it still crashes. but thanks for helping
Try to start kwirelessmonitor from a terminal using strace: strace kwirelessmonitor 2>&1 | tee /tmp/kwirelessmonitor-log.txt After crashing, check /tmp/kwirelessmonitor-log.txt for interesting output.
I'm curious what the rest of the gdb backtrace looks like that you posted (I see lines 6-12, but not 1-5). If you recompile kdelibs with debugging symbols, that might help. Also, try running kwireless monitor in gdb: gdb kwirelessmonitor run then when it crashes bt and that should give you a backtrace of where it's going awry.

I can reproduce this on ppc, too. I'm masking net-wireless/kwirelessmonitor in the mean time, and bump it to 0.5.91 for who wants to test.
I don't seem to be having problems with it. I've emerged it over a week ago and it doesn't lock up my system, very weird. I'm in the middle of remerging stuff after the gcc upgrade and now I can't emerge any version of kwireless due to the package.mask.
(In reply to comment #9) > I don't seem to be having problems with it. I've emerged it over a week ago > and it doesn't lock up my system, very weird. Same here. I've been using kwirelessmonitor for more than a year now, and it has always worked rock-solid for me. > I'm in the middle of remerging stuff after the gcc upgrade and now I can't > emerge any version of kwireless due to the package.mask. Well, just unmask it: echo net-wireless/kwirelessmonitor >> /etc/portage/package.unmask
Great timing: After a rebuild of kwirelessmonitor (I uninstalled it yesterday due to the masking) it keeps on crashing on my system as well. Might be caused by a change in some header file that was updated since the last time I installed it. Upgrading to 0.5.91 didn't help.
kwirelessmonitor is now gone from portage. kwlaninfo has superceded it.
