It would say in which source files and functions, and at what line of code
the issue happened, and possibly why it happened.

E.g., instead of
[244312.106] 0: /usr/bin/X (xorg_backtrace+0x3b) [0x80eab8b]
[244312.106] 1: /usr/bin/X (0x8048000+0x5fb38) [0x80a7b38]
[244312.106] 2: (vdso) (__kernel_rt_sigreturn+0x0) [0xffffe40c]
[244312.106] 3: /usr/bin/X (ProcUngrabKeyboard+0x10f) [0x807e0bf]
[244312.106] 4: /usr/bin/X (0x8048000+0x28167) [0x8070167]
[244312.106] 5: /usr/bin/X (0x8048000+0x1a81c) [0x806281c]
[244312.106] 6: /lib/i386-linux-gnu/libc.so.6 (__libc_start_main+0xe7)
[0xb75c7e37]
[244312.106] 7: /usr/bin/X (0x8048000+0x1a411) [0x8062411]
[244312.107] Segmentation fault at address 0x36d

it would say something like (just an example):

Program received signal SIGSEGV, Segmentation fault.
0xb7a92524 in GXDisplayVideo (pScrni=0x828bd38, id=0xb7aa9490, offset=0x17,
width=0x82a, height=0xe730, pitch=0xb7aa946c, x1=0x8289920, y1=0x0,
x2=0x0, y2=0x0, dstBox=0x82ae680, src_w=0x82a, src_h=0xe794, drw_w=0x828,
drw_h=0x8638) at amd_gx_video.c:849
