--- Comment #3 from Vincent Povirk madewokherd@gmail.com 2011-04-12 17:30:47 CDT --- Created an attachment (id=34073) --> (http://bugs.winehq.org/attachment.cgi?id=34073) log of running winecfg in a new prefix with +mountmgr
Interesting bit seems to be
warn:mountmgr:hal_thread HAL context init failed: (null)
for small values of "interesting".
