--- Comment #21 from James Huk Huk@wine.x.pl 2010-06-11 04:54:25 --- No wine does not report this unless WINEDEBUG=+all is used, and it should warn about this in the console. The solution is simple ONLY WHEN you know that the file limit is responsible. So adding a warning in the console is actually a fix , or at least an indication for the user to what is wrong. Also the severity of this "bug" is unknown - we know for sure about few apps, but there are others probably.
