Yep, suppsedly in Ubuntu it's not that easy to just get a plain old coredump file -- see below.

Googling for "ubuntu+disable+crash" turns up that your Git crashes are handled by a system-wide tool called "apport" [1].
Considering this, I would try to explore two routes:
* [1] Tells that apport has a special tool, apport-retrace, which is
said to be able to download available matching debug packages, if
any, and generate the stack traces. Basically this would do what
Thomas advised you to attempt to do using GDB.
* Try to disable apprort permanently and then crash Git normally,
so that apport does not interfere with the crash and the kernel is
able to generate a regular core file in your current directory.
Be sure to verify the core-file-size limit has a sensibly large
value in your shell before attempting to do that.

Yes, this is a viable way to try solving the problem. *But* there's a downside: the crash you're experiencing might affect later Git versions as well as yours. And if you just throw your hands there, the bug will continue to be unfixed. Hence I urge you to be a good F/OSS user and help the Git devs investigate the case.
