Works fine for me … My test project name was already "Trac Dével (ü)", now it's "Trac Dével (ü) Σχέδιο" ;-)

Can you show us the backtrace?

[ilias@…]

here it is

more detailed

Code fragment:

 179. default = None
 180. if self.parent:
 181. default = self.parent.get(section, option)
 182. current = self.parser.has_option(section, option) and \
 183. self.parser.get(section, option)
 184. if current is not False and current != default:
 185. options.append((option, current))
 186. if options:
 187. sections.append((section, sorted(options)))
 188.  
 189. fileobj = open(self.filename, 'w')

Local variables:
Name	Value
current 	'\xce\xa3\xcf\x87\xce\xad\xce\xb4\xce\xb9\xce\xbf ...
default 	u'Please add the Name'
option 	'name'
options 	[]
section 	'project'
sections 	[('account-manager', [('password_store', 'HtPasswdStore')]), ...
self 	<Configuration ...

[Christian Boos]

Ok, I see the problem (self.parent gives unicode back, and self.parser.get gives str back; the comparison promotes the str to unicode the automatic way)

[ilias@…]

but why on my site and not at yours?

[Christian Boos]

Enforce unicode comparison between current value and default value from parent config

[Christian Boos]

I didn't have a parent config (i.e no [inherit] file =...) for that environment.

Could you please try the following fix?

[ilias@…]

I've tried the fix, works fine on my side.

Thanks a lot.

[Christian Boos]

You're welcome, thanks for the report.

Fixed in [6368].
