--- Comment #5 from Rafał Mużyło galtgendo@o2.pl --- Finally got the app running long enough to get a valid result.
Now, again, I can't say I'm certain the crash is gone, but it didn't happen in quite awhile.
Yet, winegstreamer is leaking something somewhere. After a long enough run, 'too many allocated handles, not caching' from wine server becomes quite common in the output.
