Thanks for the report! Can you install Qt's (qtbase and qtdeclarative) debug symbols (or compile as debug) as well as Plasma* and KScreen debug symbols? Then please repost the backtrace again. Thanks
even will all those debug symbols, i cannot get more than: Thread 1 (Thread 0x7fe9c3e777c0 (LWP 3031)): [KCrash Handler] #5 0x00007fe9c13d25b9 in QV4::RuntimeHelpers::equalHelper(QV4::ValueRef, QV4::ValueRef) (this=0x7fe8cc7fd078) at jsruntime/qv4value_inl_p.h:52 #6 0x00007fe9c13d25b9 in QV4::RuntimeHelpers::equalHelper(QV4::ValueRef, QV4::ValueRef) (x=..., y=...) at jsruntime/qv4runtime.cpp:709 #7 0x00007fe96430754d in () #8 0x00000000031c5610 in () #9 0x0001800000000000 in () #10 0x0003000000000003 in () #11 0x00007fe900000000 in () #12 0x0000000000000000 in ()

Your QT_PLUGIN_PATH is probably wrong?
(In reply to David Edmundson from comment #4) > Your QT_PLUGIN_PATH is probably wrong? Two versions of QT5 shared the same parameters, except one is -debug and the other is -release for qt5's configure.
