Problem using pmount

[Sridhar M A <alaymari@gmail.com>]

Currently am using debian testing.

So far, I was using pmount to mount my usb drive without any issues
(am also a member of the plugdev group).

Since a couple of days, pmount started failing. Before I explain
further, the same drive can be mounted via thunar.

This is the error I am seeing:

$ pmount /dev/sdb1 mas
NTFS signature is missing.
Failed to mount '/dev/sdb1': Invalid argument
The device '/dev/sdb1' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

Error: could not delete mount point: No such file or directory.

I even formatted my pen drive, but the same problem persists. In fact,
the drive is formatted for vfat, not NTFS.

$ lsblk -o name,fstype,size,mountpoint,uuid
NAME        FSTYPE   SIZE MOUNTPOINT       UUID
sdb                  7.5G
└─sdb1      vfat     7.5G                  3BE4-3417

Could not find any bug reports about such an issue?

Any pointers will be helpful.
