--- Comment #2 from camillo.lugaresi+wine@gmail.com 2013-07-18 18:02:21 CDT --- Created attachment 45329 --> http://bugs.winehq.org/attachment.cgi?id=45329 error at wine boot and consequent infinite loop
After tracing the looping instance of wine, it turns out that the hang is related to the error that it spits out during launch (the attached file contains the error first and a callstack of the looping process second).
