Because this bug is extremly annoying, i looked a bit further into what is happening. Running the X server in gdb gives the following details on the crash:
----------snip------ Program received signal SIGSEGV, Segmentation fault. 0x08096feb in doListFontsWithInfo (client=0x8ad5d58, c=0x8b28dc8) at ../../dix/dixfonts.c:920 920 ../../dix/dixfonts.c: No such file or directory. in ../../dix/dixfonts.c (gdb) bt #0 0x08096feb in doListFontsWithInfo (client=0x8ad5d58, c=0x8b28dc8) at ../../dix/dixfonts.c:920 #1 0x08094200 in ProcessWorkQueue () at ../../dix/dixutils.c:527 #2 0x080a2766 in WaitForSomething (pClientsReady=0x8a401e0) at ../../os/WaitFor.c:169 #3 0x08080c4e in Dispatch () at ../../dix/dispatch.c:368 ----------snip------ The blameworthy code in dixfonts.c looks like this: 918 while (c->current.current_fpe < c->num_fpes) 919 { 920 fpe = c->fpe_list[c->current.current_fpe]; 921 err = Successful; So lets take a look into the ominous "c": ----------snip------ (gdb) print *c $1 = {client = 0x8b292c8, num_fpes = 145920400, fpe_list = 0x0, reply = 0x0, length = 228, current = { pattern = "-sony-fixed-medium-r-normal--16-120-100-100-c-80-iso8859-1\262\b", '\000' <repeats 192 times>, "-\000\000", patlen = 58, current_fpe = 0, max_names = 0, list_started = 1, private = 0x0}, saved = { pattern = "\b\b\b\b\t\t\t\t\n\n\n\n\v\v\v\v\f\f\f\f\r\r\r\r\r\r\r\r\016\016\016\016\017\017\017\017\017\017\017\017", '\020' <repeats 12 times>, '\021' <repeats 44 times>, '\020' <repeats 12 times>, "\017\017\017\017\017\017\017\017\016\016\016\016\r\r\r\r\r\r\r\r\f\f\f\f\v\v\v\v\n\n\n\n\t\t\t\t\b\b\b\b\a\a\a\a\006\006\006\006\005\005\005\005\004\004\004\004\003\003\003\003\001\001\001\001", '\000' <repeats 83 times>, patlen = 0, current_fpe = 0, max_names = 0, list_started = 0, private = 0x0}, savedNumFonts = 0, haveSaved = 0, savedName = 0x0} ----------snip------ Note, that c->fpe_list is NULL, while c->num_fpes contains an unreasonable value. When printing this value in hex, it actually looks like a pointer instead of the expected count. I guess, the data structure has either been corrupted somewhere or c points to something completely wrong. At this point i must give up; i don't understand enough on the interna of the x server. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in ubuntu. https://bugs.launchpad.net/bugs/683016 Title: emacs23/rxvt/xawtv/vlc crash Xorg w/ proprietary NVIDIA driver _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
