Rev 4266 Debian package got segment fault

[zhuxuan]

Debian/etch, wxGtk 2.8.4
I start CB, and adjust the layout, and exit it.
I found it can't save my layout, because I got segment fault message when exiting CB.
I use gdb backtrace CB, the following are the messages:

====================================================================

Program received signal SIGSEGV, Segmentation fault.
