saving attachement fails on sshfs filesystem

[Louis-David Mitterrand <vindex+lists-mutt-dev@xxxxxxxxxxx>]

Hello,

Using debian unstable's 1.5.13-1.1 I can no longer save attachements on 
a sshfs (fuse) partition: pressing <enter> at the save-file prompt makes 
mutt wait a few seconds after which the same prompt and default filename 
returns with no error message. Instead of saving the file mutt creates a 
.muttxxx directory for each attempt:

drwx------ 1 ldm ldm    6 2007-01-02 15:31 .mutt7mnbhX/
drwx------ 1 ldm ldm    6 2007-01-02 15:25 .muttKXRT83/

Might this be related to this recent change (debian bug #396104)?

        CVE-2006-5297:
        Race condition in the safe_open function in the Mutt mail client
        1.5.12 and earlier, when creating temporary files in an NFS
        filesystem, allows local users to overwrite arbitrary files due to
        limitations of the use of the O_EXCL flag on NFS filesystems.

        CVE-2006-5298:
        The mutt_adv_mktemp function in the Mutt mail client 1.5.12 and
        earlier does not properly verify that temporary files have been
        created with restricted permissions, which might allow local users to
        create files with weak permissions via a race condition between the
        mktemp and safe_fopen function calls.
