We have already got a bug report some time ago
(https://savannah.gnu.org/bugs/index.php?38305) but without a response
to our requests for more info. Therefore it was closed.

Here the three related questions from Rik and me:
- What language is configured in the settings dialog? Does the freeze
occur with en_US, too?
- Does the settings dialog cause this freeze, too?
- Does Octave actually crash, as in a segmentation fault and a return to
the shell prompt? Or is the first File Dialog window slow to open, but
subsequent dialogs are fine?
