--- Comment #11 from Nikolay Sivov bunglehead@gmail.com 2013-07-11 13:08:10 CDT --- I didn't mention it, you could try to reduce it even more if you start another application first with wine. For example, try to 'wine winecfg' in a separate terminal and then get another log from application, don't forget to remove old log cause new data will be appended to what's in file. Starting another application first launch some service processes that wine needs and their debug logging won't get into your log.
