Segmentation fault in menu
Recently updating our neuron tracing plugin. It's strange that my
newly compiled vaa3d fails silently with a segmentation fault when
any released plugin is evoked from the menu. However, if I added
the .so of the plugin to the quick access bar and click from there,
most plugins worked as expected.
The only thing notable was a plugin failed to be initiated at the startup of v3d as below.
PS: I am using the vaa3d compiled from the fast-forward master branch on Ubuntu16.04 & the building went well.

Searching in ./plugins ......

RE: Segmentation fault in menu
Just note that I could not reproduce this issue myself on another
machine (my laptop also with Ubuntu16.04)... Both compiled with the
precompiled qt4.7.3. Confused about the possible cause. I may make
some prints myself to provide more information.
