[Bug 1332623] Re: Thunar behaves inconsistently with USB flash drive FAT32 partitions

[MDE]

As I recall, this bug is about getting the error message "destination is
read-only" on a drive which has become read-only one time during a login
session despite remounting or inserting other drives which get the same
device name.

If you don't see this error message, then your bug is a different one.
Reading https://forum.xfce.org/viewtopic.php?pid=50502#p50502 I see no
similarities between the two cases.

I didn't verify the fix with the updated glib packages available in
bionic (2.56.x), but will do in the following days.

Title:
  Thunar behaves inconsistently with USB flash drive FAT32 partitions

Status in glib2.0 package in Ubuntu:
  Confirmed
Status in thunar package in Ubuntu:
  Fix Released

Bug description:
  I installed Xubuntu 14.04 and performed no customizations or
  reconfigurations.

  Observation:  Thunar 1.6.3 ("File Manager" from menu) on Xubuntu 14.04 handles write permission to inserted USB flash drives inconsistently:
  * I am able to create a nil file on the flash drive with Thunar and edit it.  Clearly, the flash drive is not read-only.
  * Using Thunar, I cannot copy an existing file (E.g. ~/.profile) and paste it on the flash drive - "destination is read-only" (not true!).
  * However, in a terminal window, `cp` with the flash drive as a destination succeeds.

  I tried this on drives by different manufacturers and with differing
  capacities and on two different Xubuntu 14.04 installations.

  There might be a configuration change for Thunar to allow paste to
  flash drives.  If so, this should be enabled when Thunar is installed
  as this behaviour is what users expect.

  Note: I created the FAT32 partition with `gparted` on Linux.  I also
  got the same results after creating a FAT32 partition using an MACOSX
  system.
