No, not in this type of case.

Actually I wouldn't have an issue with that had she been convicted of, say, assault. In that case it would be reasonable for the electorate to decide if her being convicted of assault makes her illegible in their eyes.

But here she has been convicted of fraudulent use of EU money to fund here own party. That money could be used to buy her votes.

France, and most EU countries I think, have strict laws about funding of political parties and campaigns in order to have a level playing field and prevent rich candidates / parties having an undue advantage. If politicians could illegally fund their campaigns beyond what is authorized that could be used to unfairly influence the vote.
