There was an incident involving an Emirates A330 at the end of last month.
The local newspapers here were rather reticent about what exactly
happened, although it was reported that the Vienna-bound airplane was in
the air for about an hour after taking off and had returned to make an
emergency landing. Curiously, it was also reported that debris from the
runway was collected by officials investigating the incident.


This is all I could find after a quick Google search:

"An Airbus A330 en route Dubai-Vienna (Flight EK127) declared an emergency
shortly after taking off on May 28, 2006. The aircraft returned for an
emergency landing at the Dubai International Airport."
