[Freewx-maint] Bug#575536: /usr/lib/libwx_gtk2u_core-2.8.so.0: segfaults in wxWindow::DoSetSize due to m_parent being NULL

[Yaroslav Halchenko]

Package: libwxgtk2.8-0
Version: 2.8.10.1-3.1~debug
Severity: important
File: /usr/lib/libwx_gtk2u_core-2.8.so.0


First of all I must confess that my setup is somewhat ... untypical -- squeeze
chroot (under lenny), and X is VNC on that box.

Ran into the problem of segfault while trying to start mayavi2.  To give you
better information I've rebuilt wx with debug support and noopt.  Segfault happens at:

I am attaching a complete script log file for that session so  you could
see an entire traceback and possibly other useful information.
