--- Comment #4 from hanska2@luukku.com --- Regression testing would be awesome, but it requires some work. You could upload your test result with 1.7.24 which is the same as last time you reported into wine database. It's good to report even the quality of the program doesnt change.
You could try 1.7.26 but I doubt it makes no difference. Some of the devs should look into that backtrace what it means.
