I have the following line in fstab: UUID=E115C9BC8BCFF563 /mnt/Data ntfs-3g permissions,users,auto,fmask=111,comment=x-gvfs-show 0 0 After the last update it leads to this volume mounting with root:root ownership. The same line without "comment=x-gvfs-show" leads to it mounting normally (except for the fact that the volume is not shown in "Devices" section in Thunar, which is exactly the purpose for which I had this option in fstab). Prior to this update this volume was mounted normally with this option. Among the packages that came in with this update is thunar-volman. It's current version is 0.8.1-3.0. I don't have a previous version in cache, so I can't roll back and check it, but it seems logical that the problem is with it, because: 1. I triple-checked ntfs-3g mounting options and rights that I have. Besides, I didn't change them lately. 2. As I said, adding/removing "comment=x-gvfs-show" causes the issue to appear/disappear. So it seems this issue is introduced with the 0.8.1-3.0 version of thunar-volman.
Thunar does not directly read /etc/stab , it's done indirectly by the package gvfs. Possibly you installed a new version of gvfs together with your new thunar ? Your bugreport should go to there. Afaik gvfs runs in userspace to make it easy to mount. No entry in fstab should be required at all. Did you try to configure your mount in e.g. gigolo ?
