Operating system: XP; steps to reproduce it:

1. start with an empty project
2. create new folder
3. right click on new folder (without clicking its [+] tree icon to expand it)
4. create new python file
5. editra crashes (the exception is handled and you get the attached traceback)
6. project browser tree shows this hierarchy:

aaa/
  untitled folder/
      untitled file.py
      untitled file.py

Of course the duplicate "untitled file.py" does not really exist on the 
filesystem.

Thanks,

I was able to reproduce the crash doing this. I made a few changes and was 
unable to
reproduce it anymore. Can you double check on your setup?

Also added extra checking to prevent that traceback related crash from 
happening. I
couldn't get that traceback to happen. But for the data to be none a tree node 
must
have been getting accessed while it was being deleted. Which could also lead to 
the
lock up and crash.

Thanks, on windows XP it seems stable now.

really, great.

It seems that when removing a node in the tree that has children nodes they 
need to
be destroyed first.

Thanks,

Cody
