there is a debug stacktrace on http://launchpadlibrarian.net/64384360/Stacktrace.txt

[Sebastien Bacher (seb128)]

Rodrigo, could you have a look to this one?

[Jean-Baptiste Lallement (jibel)]

here is the launcher with ubuntu-dark-mono icon theme activated

[Jean-Baptiste Lallement (jibel)]

and gnome-appearance-properties with all the icon themes looking the same.
We probably have 2 bugs here and the nautilus crash being a side effect of the icon theme problem.

From seb128: "to replicate this bug, remove the svg loader and try to run nautilus, or just edit the cache in /usr/lib/gdk-pixbuf-2.0/2.10.0/loaders to remove the svg loader"

Trying this as soon as my virtual machine is setup

[Sebastien Bacher (seb128)]

just for the record the bug leading to the broken situation was bug #719861

[Barry Drake (b-drake)]

Using today's daily build of the Natty LiveCD. Problem still as before even though I understood a fix had been committed.

[Barry Drake (b-drake)]

I feel that this bug is directly linked to a range of Compiz/Unity issues due to Nouveau. For me, the click on the Ubuntu icon, (top panel left-hand side), gives a window with a black outline and no menus or close 'x' button. This seems to be the above bug issue.

[Rodrigo Moya (rodrigo-moya)]

Haven't been able to replicate this on a classic desktop session nor with unity running

I'm fairly sure it links with various bug reports (typically 710377) in
which Compiz/unity break under Nouveau driver. Nautilus only crashes
when launched from a faulty Unity window. I think the problem will be
resolved when the Unity/Compiz bug is sorted. I've tried to run Natty
on four different computers so far, and all show slight variations on
the same problem. If I can help, I will.

Regards, Barry.
