[Octave-bug-tracker] [bug #38305] file dialog causes crash

[Dan Sebald]

Follow-up Comment #7, bug #38305 (project octave):

OK Thorsten, I was going to suggest you try that since that seems to be the
issue here:

http://qt-project.org/forums/viewthread/7159

The error suggests to me something where the file dialog (which translates
somehow to KDE's file dialog) is attempting to use some utility which has
already been initialized in some way.

If I understand correctly, the action you are taking and the point of the
error message coincides with this hunk of code


void
file_editor::request_open_file (void)
{
  // Open file isn't a file_editor_tab function since the file
  // editor tab has yet to be created and there is no object to
  // pass a signal to.  Hence, functionality is here.

  // Create a NonModal message.
  QFileDialog *fileDialog = new QFileDialog (this);
  fileDialog->setNameFilter (tr ("Octave Files (*.m);;All Files (*)"));
  fileDialog->setAcceptMode (QFileDialog::AcceptOpen);
  fileDialog->setViewMode (QFileDialog::Detail);
  fileDialog->setDirectory (ced);

  connect (fileDialog, SIGNAL (fileSelected (const QString&)),
           this, SLOT (request_open_file (const QString&)));

  fileDialog->setWindowModality (Qt::NonModal);
  fileDialog->setAttribute (Qt::WA_DeleteOnClose);
  fileDialog->show ();
}


If that sound right to you, could you please remove the translator from within
the argument of the second line of code?  I.e., change


  fileDialog->setNameFilter (tr ("Octave Files (*.m);;All Files (*)"));


to


  fileDialog->setNameFilter ("Octave Files (*.m);;All Files (*)");


That is the only thing I see for which there might be a conflict of two KDE
utilities around the behavior you describe.

Does that rid the error message?  That "tr" is a shorthand macro for
something, but I always wondered what exactly.
