--- Comment #3 from Sergio Callegari scallegari@arces.unibo.it --- The most important point is clearly that the issue does not stay for the stable release, i.e. that when you update from one stable release to another it happens that some components remain in an inconsistent state in one of your wine prefixes.
Yet, I don't know if there is any statistical data, but in my circle I would say that the vast majority of the wine users are on the development releases, because (1) this is what many distros ship by default; (2) the situation is so dynamic that getting bug fixes and enhancements early makes a difference; (3) the development releases have historically been rather solid. So, addressing this early (if possible) could still be helpfull to many.
