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:
QtCored4.dll!qt_message_output
QtCored4.dll!qt_message

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
