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:
