xfce-mount 0.5 plugin doesn't see the devices mounted with ivman&pmount

[Sergei Danilov]

Hi, 
I Installed 0.5 version of the plugin. 
now when my USB device mounted with ivman&mount , plugin window does
not show device in the list of mounted devices.
May be it caused by this device mounted with ivman and does not present
in the fstab? but with previous versions of the plugin(0.4.8) all was
OK with it.

mtab contains the record, mentioned device was mounted:
/dev/sdb /media/MP3\040MUVO2 vfat
rw,noexec,nosuid,nodev,quiet,shortname=mixed,uid=104,gid=1001,umask=0000,iocharset=utf8
0 0

Best regards, 
Sergei
