I'll be happy to, but I can't find any place on that wiki to report bugs. In fact there doesn't seem to be any area for the 2.3 Fc tree at all that I could find. Could you give a more specific url? > Also useful would be a stack trace of where your applications are > crashing. I tried to get a bt, but with KDE's libs being so deeply nested I couldn't get much that looked useful. I'll tack a couple of samples to the bottom of this note for what they're worth. KDE's crash handler, KCrash, seems to shield gdb from most of the details, and I couldn't find a way to break on KCrash itself. > It may well depend on the fonts you have present on your system or > the .so version of FreeType that you have, or some other unknown > variable. I'll dig in a bit and try to come up with info on all the KDE libs and the fonts installed. In the meantime, here's a quick overview of my system: gcc 3.4.3 autoconf 2.5.8 automake 1.9.6 libtool 1.5.20 KDE 3.4.2 built from source fontconfig 2.3.92 freetype2 9.8.3 X 4.5.0 binary installation teTeX 3.0 ghostscript 8.15.1 (espgs) gnu-gs-fints-std-6.0 glibc 2.2.4 linux kernel 2.4.23 Running KDE from gdb by hacking the startx script gives this backtrace: <after typing Ctl-C to get back to gdb> Program received signal SIGINT, Interrupt. 0x40191079 in wait4 () from /lib/libc.so.6 (gdb) bt #0 0x40191079 in wait4 () from /lib/libc.so.6 #1 0x40209944 in __DTOR_END__ () from /lib/libc.so.6 #2 0x080492ce in ??

Let me know where to post this stuff on the bugs.freedesktop.org site, and anything else I should persue. Cheers, Jim
