ASSERT(Failed assertion in Qt == Qt bug)

This is a general question, as it's the 2nd time it happens to me. I've got a failed assertion in Qt 4.1.1:

Quote:

---

ASSERT failure in QCoreApplication::sendEvent: "Cannot send events to objects owned by a different thread. Current thread 80651a8. Receiver '' (of type 'MyTestClass') was created in thread 80dee80", file kernel/qcoreapplication.cpp, line 291

does a failled assertion in Qt imply a Qt bug?

Not necessarily. If you use threads, make sure that you create all QObject instances* in run() and that the thread object isn't their parent. Also make sure you don't pass QObjects between threads without invoking QObject::moveToThread().

* Including instances of all classes derived from QObject, for example QSocket.
