Comment 5 for bug 1016212

I can reproduce this in testdrive with today's quantal CD image:
- select Try Ubuntu
- open terminal with Ctrl+Alt+T (qemu tablet mouse doesn't work for me in quantal)
- sudo software-properties-gtk: enable universe
- sudo apt-get update
- sudo apt-get install gtimelog
- gtimelog

It crashes on startup after printing a couple of error messages:

    (gtimelog:9287): Gtk-CRITICAL **: gtk_style_context_get_property: assertion `priv->widget != NULL || priv->widget_path != NULL' failed
    /usr/lib/python2.7/dist-packages/gi/types.py:47: Warning: /build/buildd/glib2.0-2.33.2/./gobject/gtype.c:4206: type id `0' is invalid
      return info.invoke(*args, **kwargs)
    /usr/lib/python2.7/dist-packages/gi/types.py:47: Warning: can't peek value table for type `<invalid>' which is not currently referenced
      return info.invoke(*args, **kwargs)
    Segmentation fault (core dumped)

lp:gtimelog trunk crashes in the same way

Running gtimelog with python -m trace --trace ./gtimelog tells me that the last line of code executed inside gtimelog itself is main.py:1116, which reads

    color = style.get_color(gtk.StateFlags.NORMAL)

Looks like my panel background color detection hack is broken.

I can reproduce the segfault by doing this:

    $ python
    >>> import gi
    >>> from gi.repository import Gtk
    >>> Gtk.MenuBar().get_style_context().get_color(Gtk.StateFlags.NORMAL)
