[kde-freebsd] Qt4 programs crash on user typing into the edit box

[Yuri]

After the recent ports update (from source), all qt programs started to 
crash when the user types:

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 80c007400 (LWP 101791)]
0x000000080375c05c in QApplication::x11ProcessEvent(_XEvent*) () from 
/usr/local/lib/qt4/libQtGui.so.4
(gdb)

As an experiment, I rebuilt x11-toolkits/qt4-gui with debug info, and 
with debug info crashes don't happen.
All dependencies of qt4 were rebuilt.
So now I had to install debug version of qt4-gui as a workaround.
