unity-greeter segfault in libgio-2.0.so.0.3000.1 on Lubuntu 12.04 Alpha 1

[ԜаӀtеr Ⅼарсһуnѕkі]

Testing ISOs didn't install, so in order to complete the tests (and do the auto-resize which required there to be an existent system) I opted to install Alpha 1 on my virtual machine (Lubuntu 11.10 i386 host with VirtualBox 4.1.2-dfsg-1ubuntu1). Install went peachy keen but right about where LXDM would load, I get an endless loop of the X window (initially, a larger blank window) cycling back to the framebuffer and back to the X window, etc. Checking syslog I find the segfault. Apparently I'm not the only one with this problem (http://ubuntuforums.org/showthread.php?p=11475630) although there seems to be no bug report, so here you go.

here's a glimpse of the loop as viewed in syslog:

sorry, running in recovery console this is a little bit more cumbersome ;)

Status changed to 'Confirmed' because the bug affects multiple users.

Does this still occur?

I've run Precise in VM and on various systems since its release with no problems. I also don't have the problem in Quantal, so I'd call it dead. Thanks for checking.
