I finally found some time to debug this.
This patch make xconfig crash when you try to select a menu that opens a submenu.
This is the backtrace:

For example:
'Input device support'->'Keyboards'
Maybe we shoudld just revert it? I tried to understand the code a little bit,
but no luck yet to understand how the whole thing works.
