RHBA-2010:0032 - Bug Fix Advisory

Topic

Updated gnome-vfs2 packages that resolve several issues are now available.

Description

GNOME VFS is the GNOME virtual file system. It is the foundation of the
Nautilus file manager. It provides a modular architecture, and ships with
several modules that implement support for file systems and protocols such
as HTTP and FTP, among others.

These updated gnome-vfs2 packages provide fixes for the following bugs:

• an unresolved symbol in the gnome-vfs2 library caused the

system-config-network GUI application to be unable to start. (BZ#247522)

• client applications which used the gnome-vfs2 library were unable to

search for certain paths because the search process ended as soon as it
encountered a file or directory which it was unable to read. This update
fixes this bug in gnome-vfs2 so that searches skip over unreadable files or
directories and continue as expected.

Note: a future nautilus update will be released that properly fixes this
bug in the Nautilus file manager. (BZ#432764)

• when attempting to move one or more files between two NFS mounts, the

Nautilus file manager displayed a dialog box that stated: Error: "Not on
the same file system." This error was caused by an EXDEV error in the
gnome-vfs2 file module due to rename semantics. With this update, moving a
file from one NFS mount to another succeeds as expected due to the
implementation of a proper copy-and-delete fallback routine. (BZ#438116)

• attempting to open a supported document type represented by a symbolic

link on an NFS share with the Evince document viewer failed with the
following error message:

Unable to open document
Unhandled MIME type: "application/octet-stream"

This update improves this behavior with a symbolic link check so that
Evince is now able to successfully open a link to a supported document type
when both the link and actual file are located on an NFS share. (BZ#481593)

• the gnome-vfs-daemon service reads the list of mounted devices at

/proc/mounts upon startup. If one of the device paths was not valid UTF-8,
gnome-vfs-daemon was disconnected by D-Bus when it attempted to communicate
the path over the system message bus, at which time it exited. However,
other GNOME applications would then attempt to restart gnome-vfs-daemon, at
which time the same sequence of events reoccurred, leading to a potentially
infinite loop and much extraneous CPU usage. With this update,
gnome-vfs-daemon correctly converts the information provided by
/proc/mounts into valid UTF-8 before communicating it via D-Bus, which
prevents the possibility of gnome-vfs-daemon being disconnected, exiting,
and being restarted in a continuous fashion. (BZ#486286)

• accessing a WebDAV share which contained a comma in its path name with

the Nautilus file manager resulted in a "File not found" error. This update
ensures that reserved characters in path names are properly escaped, and
thus Nautilus is able to access such paths as expected. (BZ#503112)

All GNOME users are advised to upgrade to these updated packages, which
resolve these issues. Running GNOME sessions must be restarted for the
update to take effect.
