Re: compact test case for weird filechooser behaviour

[Bartosz Kostrzewa <zoombat runbox com>]

Ok, here's a new version of the testfilechooser.cpp i sent in yesterday.
  It includes running the main iteration to update the filechooser widget...

note the output!

selecting: /home/bartek/Dokumenter/Biller/roma/100_0659.JPG
FileChooser reports: /home/bartek/Dokumenter/Biller/roma/100_0650.JPG

selecting: /home/bartek/Dokumenter/Biller/roma/100_0660.JPG
FileChooser reports: /home/bartek/Dokumenter/Biller/roma/100_0649.JPG

selecting: /home/bartek/Dokumenter/Biller/roma/100_0661.JPG
FileChooser reports: /home/bartek/Dokumenter/Biller/roma/100_0648.JPG

now, I've found that specifically the following happens:

./testfilechooser /some/dire/ctory/*


case 1:
click apply, the first file is set
click remove, filechooser hidden
click remove, filechooser show, the LAST file in that directory is selected

case 2:
click apply, the first file is set
click apply again, the second file is selected
click remove, filechooser hidden
click remove, filechooser show, the SECOND TO LAST file in that
directory is selected

etc..
