+1, I have a similar architecture and Froyo won't start, I never had a problem with Eden.

1. Debug log: http://paste.ubuntu.com/5570977/
3. #xbmc --version: XBMC Media Center 12.0 Git:fb595f2
4. #lsb_release -a: Ubuntu 12.04.2 LTS, updated on 02/27
5. i686, pentium 4
6. PPA (add-apt-repository ppa:team-xbmc/ppa)
8. http://paste.ubuntu.com/5570995/

The backtrace shows 0x0 on Thread 1, after CGUIFontTTFGL::Begin(). Could it be that there's some opengl extension that our architecture doesn't support?

#glxinfo | grep -i direct
direct rendering: Yes

You don't appear to have the nvidia drivers installed.

Same problem here http://pastebin.com/AbqSGWcP .
Eden ok. Frodo and "latest" 13 alpha segmentation fault at same place.

@Lachim, what's your hardware?
We'll probably have to hook gdb ourselves and find more info around the null pointer in the CGUIFontTTFGL class.

That doesn't mean you are good to go.

The original poster said s/he had an GF440MX card which I assume is a very old nvidia card. But has no nvidia drivers.

What about the others? What GPU? What drivers?

Hi, I dont have nvidia drivers 96xx, much troubles with new kernels, nvidia script install error, a developer of nvidia said to user in a forum (http://www.nvnews.net/vbulletin/showthread.php?t=160452) that drivers not works correctly because very old drivers.
The version "173 drivers" change the resolution and i cant see nothing, not its supported by my monitor.
Then i use nouveau drivers, that works "well" more or less. shouldn't be a problem with xbmc, but i dont know. Im a simple user of ubuntu & Lubuntu...

Sorry by my english.

Currently upgrading to 12.10 but I'm 90% sure I'm using software rendering (no GPU).

@Lachim, what's your hardware?
We'll probably have to hook gdb ourselves and find more info around the null pointer in the CGUIFontTTFGL class.

So I look at GUIFontTTFGL class and i diff it with old Eden source. There is a new calling of blend function in Begin method which is different in Eden. I replace this line by older one, compile it and voila Xbmc starts without segmentation fault.
For those, who have same problem:

GUIFontTTFGL->Begin()
Eden: glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
Frodo: glBlendFuncSeparate(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA, GL_ONE_MINUS_DST_ALPHA, GL_ONE);

I donť know yet, what's a cause of this problem. Maybe my old graphic card Intel 855gm or maybe old GL library. I still don't know if is 100% ok, but it finally starts without fault.

Still, thank you for this fine piece of software

Nice finding, glBlendFuncSeparate seems to be an OpenGL 4 function. I doubt our driver supports every OpenGL 4 function.
