rviz EnumProperty related segfault [closed]

edit

Hi

I am writing my own rviz display plugin. I wrote a few, but this is the first one that I am writing that has an EnumProperty. When I quit rviz or delete my display, a segmentation fault happens.

I comment the EnumProperty and everything is fine. Simply adding an EnumPropertyWPtr member in my class (ImageryDisplay) definition causes the problem, so it has nothing to do with how I construct it or use it.

GDB does not give me much information, except that it happens in the Display destructor:

My destructor cleans up my stuff and does:

scene_manager_->destroySceneNode(scene_node_);

Any suggestion on how to fix/debug this problem? I read the code for the builtin plugins that also use the EnumProperty, such as Pose and Grid, but did not find anything in particular.
