segfault induced by user switching

[Ian Jackson]

Binary package hint: nautilus

I switched users back and forth a few times during testing of a gutsy d-i 20071016.1 i386 oem install.

One of the users' sessions seems to have failed to shut down properly. I logged in again to be confronted with four warnings of the form
 The panel encountered a problem while loading "OAFID:GNOME_FastUserSwitchApplet"
 The panel encountered a problem while loading "OAFID:GNOME_Deskbar_Applet"
 The panel encountered a problem while loading "OAFID:GNOME_Panel_TrashApplet"
 The panel encountered a problem while loading "OAFID:GNOME_MixerApplet"

I opened a terminal (which worked) and investigated and found that the nautilus from the previous session was spinning on the CPU. It was continuously writing the following message over and over again into nautilus-debug-log.txt:
 0x8177510 2007/10/16 19:10:32.9014 (USER): debug log dumped due to signal 11

I have sent it a SIGSTOP. Please advise what steps I should take to preserve appropriate debug information.

(Launchpad suggested that this might be related to bug 150471. In answer to the question asked there: compiz is not enabled on this system because it has a blacklisted video card.)
