Memory leak in drawing

[shuerhaaken]

If I use the Ambience theme, my application leaks memory.
This happens is a custom Widget derrived from a GtkProgressBar is used, which defines it's own height.

If I use the test program with Adwaita theme there is no such issue.

Derrived widget in Vala code:
-----
using Gtk;

private class CustomProgress : ProgressBar {
    public override void get_preferred_height(out int minimum_height, out int natural_height) {
        minimum_height = natural_height = 8;
    }
}
-----

The leaking happens during rendering after the progress bar's fraction has been set. Issue come up in gtk_render_background(), gtk_render_frame() and gtk_render_activity().

I have the same error, with xnoise music player application.
Commanly the memory useg is over than 500 ~ 600MB.

Why isn't anybody answering this bug report?

Next time I should write it on a piece of paper and throw it out of the window. Same effect.

Disappointing

Is this bug still present in Trusty? I'm thinking of uploading unico to Debian repos (it has been removed due to a critical bug and the departure of the maintainer), and if this bug isn't fixed there's no point in doing it.
