Freeze while using shortcut CTRL+T and writing something with a space

Select a task in the list.
Type CTRL+T, shorcut for adding a tag

Enter
You got an error message.
Until here, normal.

Pb is that you can not validate this error box and comes back to soft.
Even with kill function, I still have soft running !!
