Summary: Bogus wxFrame assertion failure on GTK2 w/AUI

Initial Comment:
Moving from wxWidgets 2.8.6 to wxWidgets 2.8.7 (GTK2 on Fedora Core 5), we are encountering a seemingly bogus wxFrame assertion failure when docking/undocking windows using an AUI frame manager. This assertion failure occurs in src/gtk/frame.cpp(330), saying something like (m_wxwindow == NULL) in method GtkOnSize()? This assertion failure is even present in the AUI sample provided with 2.8.7. The attached screenshot illustrates the problem. I am using wxWidgets2.8.7 with GCC version 4.1.1 on Fedora Core 5, wGTK2 (I know this is an old OS but it is required for our customers, for backwards compatibility).

While I wasn't able to find any posts about this issue on the wxForum, I did find an Internet usenet groups post:
http://groups.google.com/group/comp.soft-sys.wxwindows/browse_thread/thread/3c3e0f6398e58379

Any ideas? I will have to revert to 2.8.6 until we figure this out. Again, this problem is present in the AUI sample distributed with wxWidgets.

Thanks,
Luke
