I can reproduce a crash:
- enable Ivy addon
- shift+A --> Curve --> Add Ivy To Mesh
- F6 redo
- use either "Add New Ivy" or "Add New Default Ivy" operators
- crash
this only happens on F6 redo (not T-Region last operator redo thingie)
Ivy operator has another layout.operator in its draw() which seems problematic as op is freed (see backtrace)
Not sure if this can be worked around from Ivy or if this needs to be fixed in UI code...

(note the panel bl_idname should be CURVE_PT_IvyGenPanel missed that)
If acceptable possibly could be included in 2.79a. I'll update the wiki and the release notes. If not the recursive operator calls should be commented out.
After some talks on blendercoders, what the add-on did was pretty bad and broken for years (before it caused a memory leak on exit in 2.69 for instance).
I'll keep the blender tag for now as it does touch the F6 redo menu if this happens in the future, even though this kind of storing properties in the operator draw for recursive execution should be avoided.
The fix bellow uses window manager props and update to achieve the same results as before. The biggest difference is that the instead in the menu it is located in the Tools Shelf (T) under the create Tab.
Please test if it works properly:
