emerging without gnome support 'fixes' the seg fault.
i just tried this and its working for me what video card and xorg/xfree are you using? from looks of backtrace it looks like its having a problem with loading some prefs but i didnt know celestia had any to save... if you can find out where that file is might try trashing it and see if it loads
Using an Nvidia card, XOrg 6.8.0-r1 Here is what it is trying to load: void readGConfMain(AppPreferences* p) { // This area should, in theory, have error checking p->winWidth = gconf_client_get_int(client, "/apps/celestia/winWidth", NULL); p->winHeight = gconf_client_get_int(client, "/apps/celestia/winHeight", NULL); p->winX = gconf_client_get_int(client, "/apps/celestia/winX", NULL); p->winY = gconf_client_get_int(client, "/apps/celestia/winY", NULL); p->ambientLight = gconf_client_get_float(client, "/apps/celestia/ambientLight", NULL); p->visualMagnitude = gconf_client_get_float(client, "/apps/celestia/visualMagnitude", NULL); p->showLocalTime = gconf_client_get_bool(client, "/apps/celestia/showLocalTime", NULL); p->hudDetail = gconf_client_get_int(client, "/apps/celestia/hudDetail", NULL); p->fullScreen = gconf_client_get_bool(client, "/apps/celestia/fullScreen", NULL); p->starStyle = (Renderer::StarStyle)gconf_client_get_int(client, "/apps/celestia/starStyle", NULL); p->altSurfaceName = gconf_client_get_string(client, "/apps/celestia/altSurfaceName", NULL); } I'm guessing its choaking on that p->atlSurfaceName bit as its not set. gconftool-2 -a /apps/celestia winWidth = 640 winHeight = 480 starStyle = 0 altSurfaceName = winX = -1 hudDetail = 1 winY = -1 ambientLight = 0.10000000149011612 showLocalTime = true fullScreen = false visualMagnitude = 8.5 I don't understand enough about the code in celestia to know what its doing, trying to do. But looking at it: p->altSurfaceName = ""; #ifdef GNOME readGConfMain(p); The string gets set to an empty string, then later looks like it gets NULL'd out. which strlen will barf on. Beats me.
well i looked at my configuration info and it matchs yours perhaps try --recursive-unset with gconftool on the celestia config items and see if it loads then or perhaps set a string for the altSurfaceName item and see if it works then ill look over the code for this section in the mean time and see if i can setup a quick NULL check as i cant reproduce it after i make it ill have to have you test it if your still having the problem by then
hmm i notice your on 808 glibc snapshot on another bug the user upgraded to the glibc snapshot 1006 perhaps this is also your problem ill play with this idea on my test system also
I'm having a segfault on celestia startup too. version 1.3.2. I have a radeon 9000 IGP card if that matters.

is there still an issue i can still not reproduce any segfaults with USE=gnome if anyone still has this issue i need feedback or else the bug will be closed in the next 24-48 hours
Seems to be fixed with gnome 2.8.1
works here fine indeed
some aweful long 48 hours later.....
