I reported this behavior as bug 810145. That bug's trace is slightly different, and to be fair on recent Oneiric builds I get the trace from *this* bug instead. I'm commenting here in case the other bug should be set as a duplicate of this one.
I got this in an Oneiric network installation with accessibility enabled in the preseed file by doing this in the late_command:
Hello,
I reported this behavior as bug 810145. That bug's trace is slightly different, and to be fair on recent Oneiric builds I get the trace from *this* bug instead. I'm commenting here in case the other bug should be set as a duplicate of this one.
I got this in an Oneiric network installation with accessibility enabled in the preseed file by doing this in the late_command:
gconftool-2 --set --type bool /desktop/ gnome/interface /accessibility true
I confirmed that setting that to false and then restarting the session makes the problem go away, i.e. the panel stops dying/respawning.
Let me know if more information or testing is needed or if I can help in any other way.
