Comment 2 for bug 161028

Hi there!

I am not Meethune, but I have the same problem, even with up-to-date libwnck and so on. Since I do all my compiles with -g, here comes two backtraces:

1. The one leading to the assertion:

#0 set_icon (class_group=0x29211718) at class-group.c:414
 icon = (GdkPixbuf *) 0x280cc29b
 mini_icon = (GdkPixbuf *) 0x0
 __PRETTY_FUNCTION__ = "set_icon"

The following coredump adds this on top of the latter:

This is with current bzr-checkout and libwnck 2.20.3
Can I provide more useful information? Just tell me what else I can do to help, because I really *love* awn on Linux :o)
