XRC with built in art

Hi all,

I recently put together a custom error dialog that would be used to include a 
helpful stack trace for when things go wrong. Having built it in XRCed and 
checked that everything looked as expected I fired up our application and 
loaded the dialog as normal[1]. However, when displaying the dialog in our 
application the usually transparent background area of the wxART_ERROR (which 
is created with a wxStaticBitmap in XRC) isn't transparent as it appeared in 
XRCed and is instead black (or presumably whatever the currently assigned 
background colour is). After some hunting around online I haven't been able to 
find anything useful, but was able to reproduce the error in code. It seems 
that using the following snippet causes the problem to occur:

  my $bitmap = Wx::ArtProvider::GetBitmap ( wxART_ERROR );
  my $sbitmap = new Wx::StaticBitmap ( $frame, -1, $bitmap );

Where as the following code snippet has the correct behaviour:

  my $bitmap = Wx::ArtProvider::GetIcon ( wxART_ERROR );
  my $sbitmap = new Wx::StaticBitmap ( $frame, -1, $bitmap );

I'd rather not have to rewrite it all in code as it kind of defeats the point 
of using XRC in the first place :) If anybody has any suggestions then I'm all 
ears!

Cheers,

Matt

[1] The code looks pretty much like this:

use Wx::Perl::FSHandler::UNC;
Wx::FileSystem::AddHandler( new Wx::Perl::FSHandler::UNC );
$xrc = Wx::XmlResource->new( wxXRC_USE_LOCALE );
$xrc->InitAllHandlers;
$xrc->Load( read_file( DATA_XRC ) );
my $dialog = $xrc->LoadDialog( 'dlg_error' );
$dialog->ShowModal;
