GdkPixbufLoader size-prepared troubles

[Alesh Slovak <alesh slovak avasys jp>]

Hello,

Regarding GdkPixbufLoader's size-prepared signal, the documentation claims: 
"This signal is emitted when the pixbuf loader has been fed the initial amount 
of data that is required to figure out the size of the image that it will create."

Which, to me, seems to imply that the signal is emitted only once. However, I am 
receiving it almost as frequently as the area-updated signal.

Is this a bug? Or have I read too much into the documentation? I couldn't find 
anything relevant in the gnome bugzilla.

Furthermore, the documentation states:
"Applications can call gdk_pixbuf_loader_set_size() in response to this signal 
to set the desired size to which the image should be scaled."

But when I do this, the image data never makes it into the pixbuf, although the 
pixbuf itself appears to get sized correctly.

For the record, I am using gtkmm 2.4 on Debian testing and attempting to load 
PNM data. I didn't get the feeling that this was a gtkmm specific issue, but I 
could be wrong.

Anyone have any insights?

Thanks.
