I've always use Ctrl-Shift-T for creation of new tabs. However, I am able to confirm that terminology wouldn't accept ctrl-enter as hotkeys. below is the exception at the time terminology crashed.

I've tried to reproduced that issue but it works fine for me.
Which version of Terminology are you using?

raster, there is another possible crash path at evas_image_main.c:402, would you please look at it. It would probably fix bug T2620. Thanks
