konsole with libqt5gui5-gles 5.6.1+dfsg-3ubuntu3~3 crashed with SIGSEGV (libqgtk2.so)

[Haw Loeung]

Hi,

Latest update of libqt causes konsole (and probably others) to segfault as follows:

[ 2014.545841] konsole[7294]: segfault at 0 ip 00007fe4080c4f50 sp 00007ffdef81d630 error 4 in libqgtk2.so[7fe4080a3000+4f000]

I managed to downgrade libqt5gui5-gles; only that was required to get konsole working again.

FWIW, I also tried switching to libqt5gui5 and that too segfaults:
