Bug#1002486: matlab-support: endless loop during interactive install

[Marc Lehmann]

Package: matlab-support
Version: 0.0.22
Severity: normal

Dear Maintainer,

when trying to install this package, I get a full-screen prompt saying:

   ┌─────────────────┤ MATLAB interface configuration ├──────────────────┐
   │                                                                     │
   │ No MATLAB installation found                                        │
   │                                                                     │
   │ No MATLAB executables were found in the directories you specified.  │
   │                                                                     │
   │ This package requires at least one local installation of MATLAB.    │
   │                                                                     │
   │                               <Ok>                                  │
   │                                                                     │
   └─────────────────────────────────────────────────────────────────────┘

there is only one choice, and using it results... in the same prompt. I
held down enter for about half a minute, worth about one thousand "OK"'s,
but the dialog still repappeared, so thisa seems to be an endless loop.

You can't ^Z out of it, either, so you need to log in form another
terminal and kill the process tree.
