[Interest] qtquick externaldragdrop crashing on x11 (Ubuntu 13.10)

[manish sharma]

Hi,

I ran externaldragdrop sample under qtdeclarative/examples/quick folder.
And it crashed and below is the backtrace. The internal dragdrop sample
works perfect.

I was thinking to check here before logging a ticket.

Regards,
Manish
