+ [Impact]
+ 
+ The bug prevents users from launching a second instance of gthumb.
+ 
+ This feature is sometimes useful, for example, when opening a few images
+ in a row from a file manager - it might open a new instance of gthumb.
+ 
+ In addition, second instance fails to run without any messages (unless
+ you run it from terminal), which is confusing to the users.

+ The fix had been already applied upstream a few years ago, and it would be nice to backport it to Trusty.
+ The debdiff which is attached to this report contains the backported patch.
+ 
+ [Test Case]
+ 
+ Steps to reproduce:
+ 
+ - launch one instance of gthumb from terminal: gthumb &
+ - try launching a second instance: gthumb
+ 
+ Expected result:
+ 
+ - second instance would open normally
+ 
+ What really happens:
+ 
+ - second instance shows error message and quits immediately:

+ 
+ [Regression Potential]
+ 
+ The fix had been applied upstream a few years ago, so it had been tested

+ 
+ It was also tested by Utopic/Vivid/Wily users as it was included in

+ I consider the regression potential to be low here.

+ [Original Report]
  If I right click on an "image file" in caja, select "open with", then "gthumb" :
  In Linux Mint 13 Mate 32-bit I could open/launch multiple instances of gthumb from caja
  In Linux Mint 17 Mate 32-bit I can only launch a single instance of gthumb - it seems to start, then nothing
  In Linux Mint 17 Mate 32-bit I found I could open multiple instances of gthumb only from the gthumb file menu, select "New WIndow".
  Worked in 13, not in 17 - could not find a preference (like I describe below for a similar problem with VLC Player) to solve this problem.
  
  Note: found a similar problem with VLC Player, but it turned out a
  difference in default preference setting in VLC from 13 to 17, making
  that VLC preference change (preferences/interface settings/playlist and
  instances/use only one instance when stated from file manager) solved
  the problem.

Bug description:
  [Impact]

  The bug prevents users from launching a second instance of gthumb.

  This feature is sometimes useful, for example, when opening a few
  images in a row from a file manager - it might open a new instance of
  gthumb.

  In addition, second instance fails to run without any messages (unless
  you run it from terminal), which is confusing to the users.

  The fix had been already applied upstream a few years ago, and it would be nice to backport it to Trusty.
  The debdiff which is attached to this report contains the backported patch.

  [Test Case]

  Steps to reproduce:

  - launch one instance of gthumb from terminal: gthumb &
  - try launching a second instance: gthumb

  Expected result:

  - second instance would open normally

  What really happens:

  - second instance shows error message and quits immediately:

  GDBus.Error:org.freedesktop.DBus.Error.NotSupported: Application does
  not handle command line arguments

  [Regression Potential]

  The fix had been applied upstream a few years ago, so it had been
  tested since then.

  It was also tested by Utopic/Vivid/Wily users as it was included in
  gthumb 3.2.8 in these releases.

  I consider the regression potential to be low here.
