Comment 25 for bug 918401

updates this morning:
http://paste.ubuntu.com/816825/

included:
2012-01-25 10:21:13 configure unity 5.0.0-0ubuntu3 <none>
2012-01-25 10:21:13 configure unity-greeter 0.2.0-0ubuntu5 <none>

caused repeating crash:
Jan 25 10:30:51 lubuntu acpid: client 3274[0:0] has disconnected
Jan 25 10:30:51 lubuntu acpid: client connected from 3332[0:0]

Jan 25 10:30:53 lubuntu kernel: [ 241.219985] unity-greeter[3352]: segfault at c ip 00ed0090 sp bfa02690 error 4 in libindicator3.so.7.0.0[ecc000+c000]

so now the issue isn't that the greeter isn't working but lightdm still allows functionality-- it is just plain broken.

removing unity-greeter did not improve the situation.

installing unity-greeter=0.2.0-0ubuntu4 doesn't prove successful because it can't find it though it is apparently in packages:
