I don't often use the resize command and I'm not 100% this is a TDE issue. 

I have konsole set to allow programs to resize the terminal. 

When I do something like:

resize -s 25 80

it does resize the terminal, but it also waits for me to hit enter (or something) and then complains:
resize: unknown character, exiting

This is not the behavior I normally encounter.  Normally it resizes the terminal, and clearly sets columns and lines and exports them.

I have tried this in both bash and zsh. 

This is on a box with Ubuntu 15.04 freshly installed (with just zsh and TDE added).

Hopefully someone can let me know how to make this behave normally.

Thanks in advance.
