[mythtv] crash on mythvideo-rescan

[Markus Schulz]

hello,

if i rescan my video storage group in mythvideo i got a segfault.
the following was a workaround:

diff --git a/mythtv/libs/libmythui/mythprogressdialog.cpp 
b/mythtv/libs/libmythui/mythprogressdialog.cpp
index 733d7c7..d2cb113 100644

@@ -169,6 +169,7 @@ void MythUIProgressDialog::customEvent(QEvent 
*event)
     if (event->type() == ProgressUpdateEvent::kEventType)
     {
         ProgressUpdateEvent *pue = 
dynamic_cast<ProgressUpdateEvent*>(event);
+        if (pue == NULL) return;
 
         QString message = pue->GetMessage();
         if (!message.isEmpty())


looks like the event was from a different type (dynamic_cast results to 
NULL).


regards,
