Crash with UTF32 encoding in Variables pane

Consider the following:

A simple literal string (in the example a 6-byte string), when UTF32 encoding is selected in the Variables pane, constantly make the entire IDE to crash abruptly and lose all work.
Always reproducibile by me. Anyone else can confirm?

If the value is invalid then viewing it in the debugger it causes a crash.
