Empty fields on streamtuner 0.12.3

[Gabi Kolb]

Hi,

I am trying to use streamtuner on an amd64 with Gentoo.
Everything compiles file but using the python-plugin, the fields 
in the new tabs where the radio stations appear, remain empty. 
They are present in some way, I can select them and check 
properties etc.... but I cannot see the stream name.
I tried streamtuner-python 0.1.1 and 0.1.
There are error messages on the console:

** (streamtuner:5778): CRITICAL **: file st-handler-field.c: line 61 
(st_handler_field_new): assertion `type == G_TYPE_BOOLEAN || 
type == G_TYPE_INT || type == G_TYPE_STRING || type == 
GDK_TYPE_PIXBUF || (type == G_TYPE_VALUE_ARRAY && 
(flags & ST_HANDLER_FIELD_EDITABLE) == 0)' failed

** (streamtuner:5778): CRITICAL **: file st-handler.c: line 369 
(st_handler_add_field): assertion `field != NULL' failed

this is repeated lots of times..

On a 32-bit chroot everything works fine...

Does someone know where is the problem?

Br,
