Subject: Destroying SshMasterConnection off the main thread leads to a diagnostic from Qt debug libs
Date: Tue, 23 Apr 2013 12:15:18 -0700
[Message part 1 (text/plain, inline)]
Package: x2goclient 
Version: 4.0.1.0 

Note: I'm running a debug build from 4.0.1.0 sources, linked against Qt debug libs.

When shutting down a connection (e.g. by closing the x2goclient window), the debug build of Qt gives two diagnostics when two SshMasterConnection objects are destructed:

ASSERT failure in QCoreApplication::sendEvent: "Cannot send events to objects owned by a different thread. Current thread 27050c0. Receiver '' (of type 'SshMasterConnection') was created in thread 5d7500", file kernel\qcoreapplication.cpp, line 532
ASSERT failure in QCoreApplication::sendEvent: "Cannot send events to objects owned by a different thread. Current thread 27050c0. Receiver '' (of type 'SshMasterConnection') was created in thread 5d7500", file kernel\qcoreapplication.cpp, line 532

Thread 5d7500 is the main thread.

Ignoring the assert messagebox sometimes results in a GP fault. Most of the time the app exits cleanly. I'm not getting the fault at the moment, so I don't have a callstack for you.

The callstack from the diagnostic is as follows:

Can you check, if the described issue gets fixed by a patch in bug

Hi Mike, thanks for getting back to me so quickly.  Applying the patch from bug #101 does NOT fix the problem.  

Note that this isn't a blocker for me. 

Regards,
Gary

Hallo, 
mein Name ist Phil Naidoo, Chefredakteur der ABSA Bank of South  Africa. Ich war ein sehr enger Freund von Matthias Berger, Staatsbürger  ihres Landes. Matthias Berger arbeitete mit Diamond Mine firma in Botswana zusammen. Am 19 Dezember 2011 verunglückte Matthias Berger mit seiner Familie bei einem Hubschrauberabsturz.  Alle Insassen des Hubschrauber starben bei dem Unfall. Seit dem haben wir zahlreiche Erkundigungen bei Ihre Botschaft hier in Süd Afrika und Botswana angestellt um Verwandte von Herr Matthias Berger ausfindig zu machen. Leider waren wir bisher erfolglos.
Nach zahlreichen ergebnisslosen Versuchen Herr Matthias Berger Verwandten  ausfindig zu machen, habe ich mich entschieden Ihren Namen /E-mail Addresse übers dasoertliche site ausfindig zu machen, da sie die gleiche Nationalität haben. Ich habe Sie kontaktiert um Ihnen dabei zu assistieren Anspruch auf einen Betrag von 8.2 Millionen US Dollar, hinterlassen von meinem Freund Herr Matthias Berger zu erheben, bevor es von der ABSA Bank of South Africa konfeziert wird . Die ABSA Bank of South Afrika hat mich benachrichtigt das ich einen Verwandten ausfindig machen muss oder das Geld wird innerhalb der nächsten 21 Arbeitstagen konfesziert. In meiner Position als Chefredakteur der ABSA Bank of South Afrika ist es mir Möglich das Geld auf ein gültiges ausländisches Konto zu überweien mit der Sicherung das das Geld komplett sein wird bis ich in Ihr Land komme um das Geld mit Ihnen zu teilen.
Da es mir seit Vier Jahren nicht gelungen ist Verwandschaft von Herr Matthias Berger ausfindig zu machen, versuche ich Ihr Einverständnis zu bekommen Sie als nächste Verwandten des Verstorbenen zu präsentieren da Sie die gleiche Nationalität haben und somit das Geld zu Ihnen überwiesen werden kann. Wenn Sie an meinen Vorschlag interessiert sind, können wir die Teilungsverhältnisse und Uberweisungsmodalitäten besprechen. Ich besitze alle nötigen Informationen und gesetzlichen Dokumente um Ihre Anspruchsforderung zu unterstützen falls Se sich dazu entscheiden.
Ich brauche nur Ihre ehrliche Zustimmung zur Zusammenarbeit um uns diese Transaktion zu ermöglichen. Ich garantiere Ihnen das dies nur unter legalen/ gesetzlichen Vorraussetzungen stattfinden wird.
Bitte kontaktiren Sie mich unter meiner E-mail:phil-naidoo@outlook.com
 	
Mit freundlichen Grüssen
Phil Naidoo
