gvfsd-smb: file content messed when using low-level write utilities (echo)

[potter000]

Binary package hint: gvfs

Configuration:
Ubuntu 9.10 Karmic
GNOME 2.28.0
gvfs 1.4.2 (tried building 1.5.1 - same result)

Steps to reproduce behaviour:
1. Mount a GVFS-SMB share (via smb://someserver/someshare)
2. Open terminal and cd to this share
3. Run commands:
user@host:~/.gvfs/someshare on someserver$ echo 100 > ./test
user@host:~/.gvfs/someshare on someserver$ echo 200 >> ./test
user@host:~/.gvfs/someshare on someserver$ echo 300 >> ./test
user@host:~/.gvfs/someshare on someserver$ echo 400 > ./test
Expected result:
file ./test containing 1 line with "400"
Real result:
user@host:~/.gvfs/someshare on someserver$ cat ./test
400
200
300

Additional information:
Similar behaviour is when using a text editor writing with fopen (e.g. Geany:
http://www.geany.org). When using gedit (which seems to write via
g_file_set_contents), all is OK.
I have already filed a bug to the GNOME team (https://bugzilla.gnome.org/show_bug.cgi?id=608908)
This behaviour is not reproducible with Ubuntu Jaunty (GNOME 2.26, gvfs 1.2.2), all is OK there

Thanks for the report, but there's no need to open a report on Ubuntu if you already did it on the upstream bug tracker. Linking that report and marking this as triaged, thanks.
