Hi, Just updated last evening (EET) all kde. It emerged w/o problems, but now, when I try repeatitly to switch between windows (ALT-TAB) with no windows opened in the active desktop, kwin crashes with signal 11 (SIGSEGV). I am currently emerging gdb so that I can provide the backtrace Portage 2.1_pre7-r2 (default-linux/x86/2006.0, gcc-3.4.6, glibc-2.4-r1, 2.6.16-gentoo-syko i686) ================================================================= System uname: 2.6.16-gentoo-syko i686 Intel(R) Pentium(R) 4 CPU 3.00GHz Gentoo Base System version 1.12.0_pre16 dev-lang/python: 2.4.2-r1 sys-apps/sandbox: 1.2.17 sys-devel/autoconf: 2.13, 2.59-r7 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2 sys-devel/binutils: 2.16.1-r2 sys-devel/libtool: 1.5.22 virtual/os-headers: 2.6.11-r3 ACCEPT_KEYWORDS="x86 ~x86" AUTOCLEAN="yes" CBUILD="i686-pc-linux-gnu" CFLAGS="-O3 -ffast-math -funroll-all-loops -march=pentium4 -pipe -fomit-frame-pointer" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3.5/env /usr/kde/3.5/share/config /usr/kde/3.5/shutdown /usr/kde/3/share/config /usr/share/X11/xkb /usr/share/config /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/revdep-rebuild /etc/terminfo /etc/env.d" CXXFLAGS="" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig distlocks keepwork metadata-transfer sandbox sfperms strict userpriv usersandbox" GENTOO_MIRRORS="ftp://ftp.ines.lug.ro/gentoo ftp://ftp.roedu.net/pub/mirrors/gentoo.org ftp://ftp.romnet.org/gentoo http://ftp.romnet.org/gentoo http://gentoo.osuosl.org http://www.ibiblio.org/pub/Linux/distributions/gentoo" LINGUAS="en" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync1.ro.gentoo.org/gentoo-portage" USE="x86 7zip X aac aalib acl acpi aim alsa apache2 apm audiofile avi bash-completion berkdb bindinst bitmap-fonts browserplugin bzip2 cdparanoia cdr cli crypt ctype cups curl curlwrappers dba dga dio directfb dlloader dv dvb dvd dvdr dvdread eds emboss encode expat fastbuild fbcon fdftk ffmpeg firefox flash foomaticdb force-cgi-redirect fortran ftp gd gdbm ghoto2 gif glut gpm hal iconv icq imagemagick imap imlib jabber javascript jikes jpeg jpeg2k kde kdexdeltas libg++ libwww lm_sensors mad memlimit mikmod mime ming mmx mng motif mp3 mpeg msn mysqli ncurses nls nptl nptlonly nsplugin nvidia offensive ogg openexr opengl oscar oss pam pcre pdf pdflib perl php png posix python qt quicktime readline rtc sasl scanner sdl session simplexml slp smp soap sockets sox speex spell spl sse sse2 ssl svg tcltk threads tiff tokenizer truetype truetype-fonts type1-fonts udev usb userlocales v4l vcd videos vorbis win32codecs wmf xcomposite xml xml2 xmms xosd xpm xprint xsl xv xvid yahoo zlib elibc_glibc input_devices_keyboard input_devices_mouse kernel_linux linguas_en userland_GNU video_cards_nvidia video_cards_sis video_cards_fbdev video_cards_fglrx" Unset: ASFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, LANG, LC_ALL, LDFLAGS

Same problem for me here. Seems to be code regression between 3.5.1 and 3.5.2. Downgrading to 3.5.1 fixes this problem. see http://bugs.kde.org/show_bug.cgi?id=124511
Same problem here...
-r1 is in cvs.
Sorry but this bug is not finish. This link (http://bugs.kde.org/show_bug.cgi?id=124511) add a new version of correct file. Please, can you add the new file to package ? ------------ bugs.kde.org --------------- ------- Additional Comment #8 From Markus Huschka 2006-04-01 18:05 ------- For me this patch solves the crash, but the issue that only windows from the currently active desktop are shown although the option "Traverse windows on all desktops" is activated in kcontrol, still remains. Any suggestions? ------- Additional Comment #9 From Dirk Mueller 2006-04-03 15:09 ------- I updated the patch accordingly. ------------ END bugs.kde.org ------------
