Qt5.6 application segv at gnome libs

My program links Qt 5.6.0 statically to be deployed on cross-platfroms.
Initially, the program was compiled on rhel6.8 (and it works fine). I want to run it on another rhel6.5 server. If I ssh to rhel6.5 system from rhel6.8, the program works fine. If I run the program directly from rhel6.5, it segvs at libgnome.so with stack trace:
[bt]: (1) /lib64/libpthread.so.0[0x3bdf20f7e0]
[bt]: (2) /lib64/libc.so.6[0x3bde729540]

[bt]: (8) /usr/lib64/libgnomeui-2.so.0 (gnome_icon_lookup_sync) +0x7d [0x3d61e621ed]
Finally, I get rid of this problem by re-installing Qt library with no-gtkstyle. My program works fine on both systems. The problem is that the GUI form looks downgraded. I still want to use gtkstyle GUI and it works on both platforms.
Have any idea on why segv happens? suggestions are appreciated. Thanks!
