--- Comment #5 from rmaz@gmx.net 2011-04-19 14:30:00 CDT --- I'm having the same annoying problem with wine versions 1.2.{1,2,3} and 1.3.x for months now on a Gentoo system where the dependencies were updated from rather old to very new over this time, both with distribution packages and manual installs. It used to work before that; I think it *may* have become broken when the X server went from using hal to udev; at least it happened around this time. But disabling hal support in wine, or enabling the hald daemon regardless, doesn't solve it.
However, a google search shows that the problems has appeared for people over the years. People are suspecting all kinds of things from home directory permissions to incompatible graphics drivers. A comment of one of the more lucky victims in https://bugs.launchpad.net/wine/+bug/296753 sums the general experience up nicely:
"Don't know what caused the problem. Don't know what fixed it."
I would suggest that the real bug here is the error message "open_mountmgr failed to open mount manager", which apparently is not very successful in connecting the wine-internal problem, whatever it is, to an external reality that the user has a chance to investigate and address.
