[Catalyst] Configuration of $c->log with Catalyst::Log::Log4perl

[Jochen Luig]

Hi,

I'm trying to replace Catalyst's default logger with 
Catalyst::Log::Log4perl.
Here's the relevant part of MyApp.pm:

package MyApp;

use strict;
use warnings;

use Catalyst::Runtime '5.70';

use Catalyst::Log::Log4perl;
use Catalyst qw/
        -Debug
        ConfigLoader
        Static::Simple
        
        StackTrace

        Authentication
        Authentication::Store::DBIC
        Authentication::Credential::Password
        Authorization::Roles
        Authorization::ACL

        Session
        Session::Store::FastMmap
        Session::State::Cookie

        FormValidator
        FillInForm
        I18N
        Unicode

        Email

        /;

use Sys::Hostname;
our $VERSION = '0.01';


__PACKAGE__->config( name => 'MyApp' );

__PACKAGE__->log( Catalyst::Log::Log4perl->new('myapp_logger.conf'));
__PACKAGE__->setup;

This is myapp_logger.conf:

log4perl.rootLogger=DEBUG, SCREEN

log4perl.appender.SCREEN=Log::Log4perl::Appender::Screen
log4perl.appender.SCREEN.mode=append

log4perl.appender.SCREEN.layout=PatternLayout
log4perl.appender.SCREEN.layout.ConversionPattern=[%d] %C <%p> - %m%n

After starting, the Conversion Pattern the logger actually uses looks like:

%d

Trying to find a minimal App producing the problem, I set up a Test 
Application and provided
the same config file. There the logger works as expected.
Next I went through the logger configuration in the debugger with both 
Apps up to:

Log::Log4perl::Config::BaseConfigurator::text(/usr/lib/perl5/vendor_perl/5.8.8/Log/Log4perl/Config/BaseConfigurator.pm:29):
29:                 $self->{text} = $text;

there I dumped $text which contained an array ref containing the lines 
of the above cited config file (I saved both dumps to files, and diff 
told me they were the same except for the numeric parts of the array 
refs). Thus I think I can be quite sure that the logger is initialized 
with the same config in both Apps.
Still, my original App comes up with the "%d" ConversionPattern.

So, can anyone tell me where I should continue looking for the error? 
Can anyone think of a scenario where the logger config gets messed up 
after initial configuration?

Thanks,

Jochen
