[PyQt] QFileSystemModel, rename and delete problemes

[Jean Dalmayrac]

Hi all,
I'm having troubles while trying to rename and delete file using the code below.
For information, the folder "D:/test" contains a subfolder named MyFolder which 
contains a file named MyFile.

Expanding "MyFolder", renaming it as "MyFolder2" and then removing "MyFile" 
gives the message :
QFileSystemWatcher: failed to add paths: D:/test/MyFolder
And MyFile is still in the treeview but not on my file system.

I'm using python 2.6.0 and PyQt 4.5.4

Thanks for the help

Jean
