well after reading your comments ,i managed to talk to marko ( the developer of this app ) and he told me that cuz of certain issues he couldnt maintain this application .
issues mainly are :
1- only 3 developers ,no more no less
2-maemo is way too old for developers
But he also said that if some one could ask for any help to maintain quickflickr for N900 ,he could offer a serious help .
All we need is a volunteer right now who knows a little too much about Qt ,feel free to ask him for any help

i hope some one can do this job and quickflickr will be perfect for maemo5 by then .
ciao
