Adjusting User-Parameters crashes Natron (on OSX)

Problem

See video for better presentation. When I try to adjust User Parameters, e.g. change defaults of knobs or adjust starting of new lines, Natron crashes as soon as I close the User-Parameters dialogue box. Tested in Natron 2.3.4 and the Snapshot from 171215, 1:10h

Expected behavior: [What you expected to happen]

• changes are processed and Natron doesn't crash

Actual behavior: [What actually happened]

• Natron crashes

  • If your problem is a crash in an official release/snapshot, please include verbose output from the application from a terminal if possible. If you also submitted a crash report, indicate the CrashID if possible. I have no idea how to start Natron with verbose output :( Crash ID = 43F9C238-78CB-4D43-8B1F-65150231A856

Steps to Reproduce

1. Create User-Parameters for e.g. a PyPlug
2. Create a Parameter, e.g. picking a knob inside the Pyplug
3. Change a default value on this knob
4. Close the User-Parameters window
5. Crash

I quickly tested on Win10 Pro, here it doesn't crash. Seems to be an OSX issue then!
