Hi all, and thanks for reporting this bug. This crash happens when the signon-ui process is terminated, which usually happens at the end of a session. For this reason, the bug reporter catches this crash at the beginning of the next session: that's why it appears that the crash happened on login.

I have a fix almost ready, stay tuned! :-)

PS @jerrylamos: please do not reinstall! This bug, although annoying, is totally harmless, and reinstalling won't make it go away.
