Thanks for reporting.

I tried a few times but failed to reproduce.  Is it reproduciable for you ?

The problematic line should be :     

     _image = new Character[_imageSize + 1];

But I really don't understand how the described action would cause crash.

Not at the moment.    I'll add another report to this bug number if it
happens again.   May have had to do with output scrolling during zero
resize . . . not sure!    I just tried again with same exact setup (3
overlapping konsoles with 3 different custom profiles, resizing one to
zero height) and nothing happened.

When the crash occurred though, the top of the window I was resizing
vertically actually disappeared into the bottom taskbar, which was
striking and noticeable.   Right now, with no crash, the top of the
window reaches a minimum size.   The konsole that caused the crash
went all the way into the bottom taskbar.

I'm unable to reproduce this using Konsole 15 on KDE5/KF5.
