It happens every time and immediately after invoking the program (before a window even appears). I haven't been able to reproduce it with any other application. I'm attaching a gdb backtrace collected according to these instructions: http://wiki.x.org/wiki/Development/Documentation/ServerDebugging?highlight=(segmentation)|(fault) Since it looks like I only get one attachment, see below for an excerpt from Xorg.0.log with a backtrace. There's also a gdb trace from lxterminal showing that it exits without a seg fault. Here's some version info for my system: lxterminal 0.1.7-1 lxde-common 0.5.0-1 kernel 2.6.34-ARCH $ X -version X.Org X Server 1.8.0 Release Date: 2010-04-02 X Protocol Version 11, Revision 0 Build Operating System: Linux 2.6.34-ARCH i686 Current Operating System: Linux deimos 2.6.34-ARCH #1 SMP PREEMPT Sat Jun 19 13:06:16 CEST 2010 i686 Kernel command line: root=/dev/disk/by-uuid/97258355-411c-456d-9ff4-d686b0a3408d ro Build Date: 01 July 2010 10:29:43PM Current version of pixman: 0.18.2 ### excerpt from Xorg.0.log: [ 4480.061] Backtrace: [ 4480.061] 0: /usr/bin/X (xorg_backtrace+0x3b) [0x80df05b] [ 4480.062] 1: /usr/bin/X (0x8048000+0x63da5) [0x80abda5] [ 4480.062] 2: (vdso) (__kernel_rt_sigreturn+0x0) [0xb788340c] [ 4480.062] 3: /usr/lib/xorg/modules/libfb.so (image_from_pict+0x3b8) [0xb72e6a58] [ 4480.062] 4: /usr/lib/xorg/modules/libfb.so (fbComposite+0x121) [0xb72e6c51] [ 4480.062] 5: /usr/bin/X (0x8048000+0xc7053) [0x810f053] [ 4480.062] 6: /usr/bin/X (CompositePicture+0x290) [0x8103710] [ 4480.062] 7: /usr/bin/X (0x8048000+0x12f0a2) [0x81770a2] [ 4480.062] 8: /usr/bin/X (0x8048000+0x12eea8) [0x8176ea8] [ 4480.063] 9: /usr/bin/X (0x8048000+0x12eea8) [0x8176ea8] [ 4480.063] 10: /usr/bin/X (0x8048000+0x9885f) [0x80e085f] [ 4480.063] 11: /usr/bin/X (BlockHandler+0x58) [0x80921f8] [ 4480.063] 12: /usr/bin/X (WaitForSomething+0x10c) [0x80a7fec] [ 4480.063] 13: /usr/bin/X (0x8048000+0x214d0) [0x80694d0] [ 4480.063] 14: /usr/bin/X (0x8048000+0x1a4b5) [0x80624b5] [ 4480.063] 15: /lib/libc.so.6 (__libc_start_main+0xe6) [0xb75c5c76] [ 4480.064] 16: /usr/bin/X (0x8048000+0x1a0a1) [0x80620a1] [ 4480.064] Segmentation fault at address 0x20 [ 4480.064] Fatal server error: [ 4480.064] Caught signal 11 (Segmentation fault).
