I think there's interest. Have given a look at your modifications and
have these comments:
+# If GConf is not available, automatic server authentication is disabled.
+ import gconf
was automatic server authentication working in any way in 0.82? If so,
I guess we need to fix it (maybe we were using something else than
GConf back then?)
+ client = gconf.client_get_default()
+ except NameError:
I would define HAS_GCONF, like you have done with the toolbars.
+if not NEW_TOOLBARS:
+ _TOOLBAR_EDIT = 1
+ _TOOLBAR_BROWSE = 2
I think we should try to not mix the main code with the compatibility
one. Otherwise the code in activities will get quite more messy and
when we decide to drop some of it we'll have more risk to introduce
