Start-Transcript isn't usable anymore from ISE, and breaks the host

I've used Start-Transcript for some time, and it suddenly has stopped being usable from ISE.

This should speak for itself:

PS ~> cd c:/tmp/somedir

PS C:/tmp/somedir> ls

    Directory: C:\tmp\somedir

Mode                LastWriteTime         Length Name
----                -------------         ------ ----
d-----       2016/01/18     13:35                subdir
d-----       2016/01/18     13:35                suf
-a----       2013/11/07     14:12              0 bar.exe
-a----       2013/11/07     14:08              0 bar.txt
-a----       2013/11/07     14:08              0 foo.exe
-a----       2013/11/07     14:08              0 foo.ini
-a----       2013/11/07     14:08              0 foo.txt
PS C:/tmp/somedir> start-transcript
Transcript started, output file is C:\private_sba\NET\DOC\PowerShell_transcript.SBA1446.FuvZcPMm.20160413093213.txt

PS C:/tmp/somedir> ls
PS C:/tmp/somedir> stop-transcript
PS C:/tmp/somedir> ls
PS C:/tmp/somedir> 

After the attempt to use Start/Stop-Transcript, the host doesn't show any output anymore!

The transcript contains:

FWIW: I have ISE Preview 5.1.1 installed side-by-side with RTM ISE. Same behavior there.

Any clue?
