crashed after reboot and external vnc connection try

reboot
login

try to connect remotely via vncviewer on another pc

changing the password does nothing.

Thanks for your bug. Could you get a backtrace with gdb and vino-dbgsym from "deb http://people.ubuntu.com/~pitti/ddebs edgy main" installed?
- gdb -p $(pidof vino-server)
(gdb) continue
make it crash
(gdb) thread apply all bt

Please don't abuse bug tags. A vino bug doesn't need a "vino" tag, if it's filled on the vino package we already know that's a vino bug by example

here is what was displayed right after I tried my password and it didn't work

Confirmed, might be a gconf issue, debug backtrace:
