This is with the latest KDE from errata (kdebase-2.2.2-1). When I log in and KDE starts up, kicker segfaults. Here's the backtrace: (no debugging symbols found)...(no debugging symbols found)... 0x40e4cca9 in __wait4 () from /lib/i686/libc.so.6 #0 0x40e4cca9 in __wait4 () from /lib/i686/libc.so.6 #1 0x40ec86b4 in __DTOR_END__ () from /lib/i686/libc.so.6 #2 0x405fd1e8 in KCrash::defaultCrashHandler () from /usr/lib/libkdecore.so.3 #3 <signal handler called> #4 0x4000ad2a in _dl_relocate_object () at dl-reloc.c:75 #5 0x40eab659 in dl_open_worker (a=0xbfffc6f0) at dl-open.c:294 #6 0x4000d7b3 in _dl_catch_error (objname=0xbfffc6e8, errstring=0xbfffc6ec, operate=0x40eab190 <dl_open_worker>, args=0xbfffc6f0) at dl-error.c:152 #7 0x40eab7ae in _dl_open (file=0x816c380 "/usr/lib/libtaskbarapplet.so.1", mode=-2147483647, caller=0x406775d5) at dl-open.c:407 #8 0x406d1375 in dlopen_doit (a=0xbfffc860) at dlopen.c:39 #9 0x4000d7b3 in _dl_catch_error (objname=0x406d31c4, errstring=0x406d31c8, operate=0x406d1340 <dlopen_doit>, args=0xbfffc860) at dl-error.c:152 #10 0x406d16fb in _dlerror_run (operate=0x406d1340 <dlopen_doit>, args=0xbfffc860) at dlerror.c:130 #11 0x406d1326 in __dlopen_check ( file=0x816c380 "/usr/lib/libtaskbarapplet.so.1", mode=1) at dlopen.c:53 #12 0x406775d5 in sys_dl_open () from /usr/lib/libkdecore.so.3 #13 0x40674de0 in tryall_dlopen () from /usr/lib/libkdecore.so.3 #14 0x40674f01 in find_module () from /usr/lib/libkdecore.so.3 #15 0x40675f81 in lt_dlopen () from /usr/lib/libkdecore.so.3 #16 0x4103b800 in KickerPluginManager::loadApplet () from /usr/lib/kicker.so #17 0x41060093 in InternalAppletContainer::InternalAppletContainer () from /usr/lib/kicker.so #18 0x4104d4bd in ContainerArea::defaultContainerConfig () from /usr/lib/kicker.so #19 0x4104a529 in ContainerArea::init () from /usr/lib/kicker.so #20 0x41047dd2 in Panel::Panel () from /usr/lib/kicker.so #21 0x41046d52 in KickerApp::KickerApp () from /usr/lib/kicker.so #22 0x41047476 in main () from /usr/lib/kicker.so #23 0x0804d0c4 in strcpy () #24 0x0804dca9 in strcpy () #25 0x0804e136 in strcpy () #26 0x0804f5a8 in strcpy () #27 0x40dae627 in __libc_start_main (main=0x804ef70 <strcpy+16888>, argc=3, ubp_av=0xbfffe974, init=0x804a4d0 <_init>, fini=0x804fd10 <_fini>, rtld_fini=0x4000dcc4 <_dl_fini>, stack_end=0xbfffe96c) at ../sysdeps/generic/libc-start.c:129
By any chance, are you using an NVidia or Neomagic graphics card? In that case, you need to turn off Antialiasing (X bug).
It is an NVidia card (TNT2). Does it help to use the binary drivers from NVidia, or the open source drivers, or is anti-aliasing just always broken no matter what driver is used?
I don't have an NVidia card, so I can't tell. Removing ~/.kde/share/config/kdeglobals should "fix" the problem by disabling antialiasing, though.
