Latest(ish) revision doesn't start, Linux x86_64

[FLHerne]

I compiled the latest revision on Linux Mint 13, x86_64, using gcc 4.6.3. No compile errors.

When run, it opens a window in which I can (very briefly) see the main menu, then crashes.

Alpha 10 as installed from the PPA works fine.

CPU is a Pentium D, graphics is a Radeon 7770 using the proprietary drivers.

Output to the console, when run on its own and using gdb:

We use SSE is some places for optimisation, but that can't be the problem because your CPU supports it.

Something must be calling a function pointer that is either NULL or undefined. If that error is accurate, this probably takes place inside Nvidia's texture conversion library.

A function pointer could be undefined if the linker fails... so my advice for now is to clear-workspaces, update-workspaces and then try running "make; make", to check if any errors come up. (basically, have you tried turning it off and on again )
