There is no doubt that France is overly bureaucratic — but having lived there for almost 25 years, I've only heard about a handful of corruption cases.
The corruption I've seen isn't actual corruption as it isn't inhibiting the proper processes, however a lot of the government officials seem to be prone to 'doing favors' in receipt of something. I've seen this in the UK and Canada, but France seems to be more accepting of it.
