after lot of googling, realized problem caused having qt in path , loading 1 first causing both windows qt modules , maya qt modules loaded , should try ensuring maya’s path first picked proper qt.

is there way resolve issue?

i started plugin debugging. started removing qt_libraries linkages in cmake script , replaced them ones located in maya(they located in /applications/autodesk/maya2013/maya.app/contents/macos/). solved problem.

update : mac os specific. remember check same in other oses too.
