12.1 Konsole crashes at tab closing


I usually open up to 10 tabs in one or two Konsole 2.7.2 windows using split view. When I right click ‘Close Tab’, the whole Konsole terminal crashes. It doesn’t happen all the time but I have got this problem a few times since the continuous running of this recently installed 12.1 KDE 4.7.2 r5 for three weeks. It’s a pain to re-open everything from las time. Using Ctrl+Shift+W to close a tab doesn’t work either. I’m wondering if anyone has got this annoying bug.
