ASSERT failed in widgets/strategydesigner.py?

[Yichun]

I am getting

ASSERT: "index >= 0 && index < count()" in file widgets/qcombobox.cpp,
line 2013
Aborted

messages when playing in Strategy Designers, specifically, I find I am
able to create a new callable under another callable (maybe doesn't
make sense at all), but when clicking on that child-callable, the
above assertion error was printed and the program quits.

I am still trying to figure out the relationship between strategies,
runners, tickers and callables.

Troy, in the head of trunk wigets/callableselectwidget.py 247: why do
we call self.callableType.removeItem()? I guess I still do not
understand the reason, but if we click on any callable a second time,
then this error will happen.

I get nothing like that. I can click around and poke at it but never
an assertion error, exception, or segfault.

Using qt-4.3.2-r1 and PyQt4-4.3.3.

Runner: execute a callable in a specific way. Ticker: run time
series data and series indexing. Callable: some code to call, may
trade on the account or not. The idea is to separate the abstractions
of strategy code, strategy data, and strategy execution. Once
separated, they can be chosen, saved, loaded, and run.

I'll admit freely that this is a bit nebulous.

I've changed back to qt 4.3.2, but the error keeps the same:

The above info is printed when I do the following step:
1. Create a Runner.
2. Create a callable under this Runner
3. Click the callable once
4. Click the callable a second time.

Note in the log, for a second click on the callable, it is different
than what's printed out in the first click. I'll look at it again
later.
