It is really hard to know for sure what is causing the crash just from
looking at this code. Is it a complete crash of Maya or just a python
exception?
Your code is using an approach that is much harder to reason about, where
you are using lots and lots of introspection to find a child of this or
that widget with this or that type or object name. If these were properly
composed as more custom classes then you could ask the widget for the thing
you need. An example of a possible problem is where you are looping on the
tab to find the current widget and then get the child and layout and check
the name. Now that you have added a scroll widget in the middle, it would
appear you aren't looking deep enough in the widget hierarchy anymore.
Other issues could be not setting object names on layouts. Or the fact that
you use dict.keys()[0] everywhere when a dict makes no guarantee of being
ordered. So this could be a bug now, or later, and/or break when you run
this in py3.
There are also lots of redundant nested dictionary lookups in the same
function body would could lead to a mistake.
My suggestion is to try and reduce your problem to the absolute smallest
amount of code. This will help isolate the difference between success and
crashing.
