[Question] Crash if Url is incomplete

MeerMusik

Good Evening Forum.
I have the following strange Problem:

When the Url contains only Strings like ftp:/, ftp://, http:/, http:// etc, the whole Application crashes. I wrote an very simple if else Checkpoint:

if(errorTestString.endsWith("ftp:/", Qt::CaseInsensitive) || errorTestString.endsWith("ftp://", Qt::CaseInsensitive)
|| errorTestString.endsWith("ftps:/", Qt::CaseInsensitive) || errorTestString.endsWith("ftps://", Qt::CaseInsensitive)
|| errorTestString.endsWith("http:/", Qt::CaseInsensitive) || errorTestString.endsWith("http://", Qt::CaseInsensitive)
|| errorTestString.endsWith("https:/", Qt::CaseInsensitive) || errorTestString.endsWith("https://", Qt::CaseInsensitive))
{
    //    QWebEnginePage::WebAction stopOnError;
    //stopOnError = QWebEnginePage::Stop;
    m_BrowserModule->triggerPageAction(QWebEnginePage::Stop, true);
  //m_BrowserModule->triggerPageAction(QWebEnginePage::Stop);

    QMessageBox::critical(this, "Invalid Url", "Please check Url");
     // m_BrowserModule->triggerPageAction(stopOnError);
     //m_BrowserModule->load(QUrl("www.google.de"));
    }
else if(!errorTestString.endsWith("ftp:/", Qt::CaseInsensitive) || !errorTestString.endsWith("ftp://", Qt::CaseInsensitive) || !errorTestString.endsWith("ftps:/", Qt::CaseInsensitive) || !errorTestString.endsWith("ftps://", Qt::CaseInsensitive)
|| !errorTestString.endsWith("http:/", Qt::CaseInsensitive) || !errorTestString.endsWith("http://", Qt::CaseInsensitive)
|| !errorTestString.endsWith("https:/", Qt::CaseInsensitive) || !errorTestString.endsWith("https://", Qt::CaseInsensitive))
{
 m_BrowserModule->load(loadEnteredUrl);
}

The Error Message in Debug Mode is:

[1209/200048:FATAL:gurl.cc(177)] Check failed: false. Trying to get the spec of an invalid URL!

The program has unexpectedly finished.

The Error Message in Release Mode is:

[1209/200239:FATAL:navigation_controller_impl.cc(927)] Check failed: active_entry->site_instance() == rfh->GetSiteInstance(). 
The program has unexpectedly finished.

I know, it is unlikely that someone types only i.e. ftp:// but I know that I sometimes accidently hit the Enter Button. So it should not crash the whole Application. That is complete BS. If it is only a String like 'abc', you get the normal ERR_NAME_NOT_RESOLVED Page.

The Problem is, that calling the Stop Trigger to Stop loading the Page/Url, is already too late. The if else Checkpoint gets hit, but the Application crashes after that.
Thanks!
