Viewing mounted network share after losing network crashes nautilus

[marcog]

Viewing a mounted samba share after losing and then regaining network access crashes nautilus.

Steps to reproduce:
1. Connect to network
2. Mount smb://pc/share from nautilus (I use a nautilus bookmark for this)
3. Explore the mounted share
4. Disconnect from network
5. Wait some time (this might require suspending and then resuming)
6. Connect to network (the same as before, so the share should still be accessible)
7. Attempt to explore the mounted share

Expected result: Either the network share should be unmounted when the connection is lost, or better it should be re-mounted when regaining network access, or even nautilus throwing a warning that the connection to the server was lost would be acceptable.

Actual result: Nautilus crashes.

Release of Ubuntu: Latest lucid (although this also occurs on karmic)

Package versions: gvfs 1.5.5-0ubuntu2; nautilus 1:2.29.92.1-0ubuntu4

Thank you for taking the time to report this bug and helping to make Ubuntu better. However, your crash report is either missing or challenging to deal with as a '.crash' file. Please follow these instructions to have apport report a new bug about your crash that can be dealt with by the automatic retracer.

 If you are running the Ubuntu Stable Release you might need to enable apport in /etc/default/apport and restart.

 If you are using Ubuntu with the Gnome desktop environment - launch nautilus and navigate to your /var/crash directory and double click on the crash report you wish to submit.

 If you are using Kubuntu or Xubuntu you can file the crash using /usr/share/apport/apport-qt --crash-file=/var/crash/_my_crash_report.crash in a terminal - where _my_crash_report.crash is the crash you would like to report.
 I'm closing this bug report since the process outlined above will automatically open a new bug report which can then dealt with more efficiently. Thanks in advance for your cooperation and understanding.

apport fails to report the bug with the following error:

"The problem cannot be reported:

The program crashed on an assertion failure, but the message could not be retrieved. Apport does not support reporting these crashes."

I have attached the .crash file.

Could you get a stracktrace using gdb?

Below is a stacktrace as requested. I don't have the debug symbols, so I'm not sure how useful it is. If you can point me to the packages with debug symbols or whatever else is required to get them I will do so.
