[Qt-interest] OpenCV2 + Qt crashes on GUI applications

[Valentin Heinitz]

Hello,

console but not GUI? You could check, if some GUI elements / QObjects 
from GUI thread are accessed directly from
another thread (e.g. from 3dr part library). If so, consider forwarding 
your data via event queue or polling from GUI thread.
Regards.
