I've attached an example. I've added three additional arguments to the
custom widget and press "Apply" after adding. In the next step I've
saved the design and closed the application. I reopen the design and
checked the arguments. All are listed with the same name as I expected.

What do you enter into the arguments input fields?

I could simplify the steps to reproduce. It looks like a more generic
issue.

 1. Create a new wxGlade project
 2. Create a new frame
 3. Right click to the sizer in the tree window and add a slot
 4. Right click in the design window and remove the slot at the bottom
 5. Change the focus back to main window
 6. Application crashes

$ gdb --args python2 ./wxglade.py
(gdb) run
(gdb) bt

Could you check if you segfault looks similar?
