Bug Since 5.2, any Linux build crashes on startup

I'm not sure if this is is the right forum to post problems with linux export (not the editor), but I hope I can get some help here anyway.

When I create a new empty project with 5.2.3 and run the build on Ubuntu 12.04, it crashes immediately at startup. Builds made with older versions (4.x, last I know is 5.1.3p3) work without any problem on the same machine.

Here's the crash log:

Ok, seems like the issue is Antialiasing... which is on by default. When switched on, the game crashes on startup. I remember before AA just didn't work on linux, but it also didn't crash the game.

Is this a known issue?

 

From looking at that, it looks like it re-initializes the graphics hardware twice, with one of the two FBConfigs having anti-aliasing working. (or at least detected) That may be the cause of the crash.

as for being in the wrong section... this place is more for the experimental Linux build of the editor, so it technically is the wrong section. (As far as I know, you post in the general support section for issues like this, I have no idea otherwise) Still, being that a big happy Linux penguin is one of the most visible things possible, you're forgiven. (Hopefully... @hippocoder? Any ideas?)
