In France it's called a "faute grave" or "faute lourde" and according to the government's website the following reasons would be acceptable, although some are more straightforward to justify than others in case of litigation:
Faute grave:
* Being drunk during work hours
* Not coming to work without a reason
* Insubordination (refusing to do work included in your contract)
* Harassment, violence, insults
* Theft on company grounds
Faute lourde:
* Keeping non-striking employees from entering company grounds
* Intentional destruction of company equipment
* Physical violence and death threats against your employer
* Kidnapping colleagues (lol)
* Stealing your employer's clients
* Divulging secret or confidential IP
Like all legal frameworks there is some room for interpretation, I'm not an expert on the matter, it's only a translation of the government website.
I've worked in a few places where occasionally a few bottles of red would be consumed during team lunch so not all companies have the same interpretation of what a fireable offense is.
