#738 #735 Iterating over edges after ctrl+Z

[Benjamin]

Rev. 9790, OSX 10.8.4

I've got an issue while iterating over the edges of my graph after ctrl+Z (Python).
The piece of code:

for e in self.sg.getOutEdges(n):
n2 = self.sg.opposite(e, n)

tells me:

Exception: Edge with id 150935 does not belong to graph "unnamed" (id 16)

which is rather strange since I'm iterating over these same edges...

Note this does not happen when executing the script on the first time, but only after ctrl+Z
This is quite problematic, forcing me to close and reopen my project whenever I'm editing the script.
