[pkg-lxqt-devel] Bug#928721: Avoid freeze for DBusActivatable apps

[Alf Gaida]

Package: libqt5xdg3
Version: 3.4.0~13-ga0c8e32-1
Severity: important
Tags: patch

For case when the DBusActivatable application is unresponsive the
startDetached() can block for a long time (the Qt default 25s DBus
timeout). Blocking can't be avoided while using QDBusInterface, because
the object can block directly in its contructor.

So we use the generated interface class and set the timeout for the DBus
call to 1500ms (can be overriden env variable QTXDG_DBUSACTIVATE_TIMEOUT).
