Other information:
removing the nautilus-python package from my ubuntu dapper "fixed" this ;)

Comment 2 Gustavo Carneiro 2006-01-23 17:32:13 UTC

"IA__g_type_module_unuse"
I suspect recent nautilus versions started to suddenly shutdown extension modules  during startup, for some weird reason, and I'm not sure nautilus-python supports that very well.

Comment 3 Gustavo Carneiro 2006-01-24 23:14:57 UTC

There was a problem with error handling and reporting in nautilus-python.  I fixed that in CVS.  With that fixed, now I see in the terminal that launches nautilus:
-----------------
nautilus-python:init_pygobject
Error in sys.excepthook:
Traceback (most recent call last):

(nautilus:1690): Nautilus-Python-WARNING **: could not import gobject
-----------------

And now at least module shutdown doesn't crash nautilus, and I suspect I know what's causing this.  It looks like nautilus extensions are now being loaded with local symbol visibility, instead of global.  I can't find any proof of this on the nautilus ChangeLog, but it's what it looks like.

Comment 4 Gustavo Carneiro 2006-01-25 00:14:44 UTC

Finally found the ChangeLog entry:

	* libnautilus-private/nautilus-module.c (nautilus_module_load):
	open modules G_MODULE_BIND_LOCAL
