It's not theoretical. It's quite easy to run into that issue: if the mutex =
is=20
unlocked for a callback, the other thread will not be able to send the=20
message. It will fail.

I've seen krunner crashing because of this. That happens because the D-Bus=
=20
calls are sent by several threads in response to the same event: the user=20
typing.

Anyway, QtDBus is resistant to the change and wouldn't have problems with t=
he=20
patch. The problem are other bindings and low-level apps.
