Snowberry error

I have a problem. Downloaded Doomsday and Snowberry
Compiled Doomsday (had to find CMakeLists.txt!)
And.. snowberry doesn't start

Here is its:

Traceback (most recent call last):

self.containerSizer.AddStretchSpacer(self.weight)

What is wrong?

I also get the same error (snowberry used to work) might be because of a newer version of python?

Digging around on my own, because I'm seeing this issue as well, I'm inclined to believe that it has more to do with a change to wxPython instead of to Python itself. Mostly because back in Jan/Feb when I was on my first attempt with getting this software running cleanly from a compile, I was able to get Snowberry to work with no issues. However, I think I may have been using wxPython 2.6. Maybe even 2.4. But downgrading tonight to check that, and digging through the wxPython website, I cannot confirm this one to be the case.

According to the wxWidgets documentation for ver 2.8.4, wxBoxSizer is derived from wxSizer which implements the wxSizer::AddStretchSpacer(int prop) pure virtual method, which is simply an alternative means of calling wxSizer::Add(0, 0, prop). However, looking at the same documentation, there does not appear to be a version of wxSizer::Add() which accepts three parameters!

And therein lies a problem. I know that snowberry worked fine when I had beta5 running before, so I'm going to download that source and check how the area.py file reads for that section. I don't really know Python, so this could be interesting, but I did notice that this error is occurring at this spot:

        if self.expanding:
            self.containerSizer.AddStretchSpacer(self.weight)
        else:
            self.containerSizer.Add((0, 0), self.weight, self._getLayoutFlags(),
                                    self.border)
        pass

Earlier on, self.expanding is set to True, and the only other place prior to that where it can be something else, it's being set to "expanding", which I can't tell where that was defined. So working from just basic programming knowledge, this almost looks like unless wxBoxSizer gains the AddStretchSpacer function, snowberry's never getting past this point. At least not for Linux. (I can't test the other OS's.)

As a test just after my last post, I commented out everything except this line:

self.containerSizer.Add((0, 0), self.weight, self._getLayoutFlags(), self.border)

And Snowberry starts right up. A bit of a hack workaround, but it allows Snowberry to run with no visible issues yet. I'll update if anything else appears to go wrong.
