If I start kdevelop on consolle when opening a project that crash I will see
this output:

====================================================
kdecore (KAccel): WARNING: KKeySequence::init( seq ): key[0] is null.
kdecore (KAccel): WARNING: KKeySequence::init( seq ): key[0] is null.
fun: f1()
bar1 called
fun: f2()
bar2 called
QGArray::at: Absolute index 0 out of range
KCrash: Application 'kdevelop' crashing...
====================================================

My Workaround n1:
if I set IDEAI editor interface and try to open that project again 
it work fine an than I can return on childframe interface successfully.

My Workaround n2:
on consolle, go into directory of the project an open it directly:
  kdevelop myproject.kdevelop

Sorry, I have no idea how reproduce it, it is strange.
..may be a number of files openened into a project that I try to load??

NOTE: on consolle the message "QGArray::at: Absolute index 0 out of range"
appear only when kdevelop crash.
