[maemo-developers] [maemo-developers] Scirocco 2.1 Installer - bad trap

[From: arne99]

Hello all,

i am actually trying to use installer from scirocco 2.1 release:
Here you can see what happens under Ubunto - terminal:

arne99 at arne99-desktop:~/Desktop$ chmod 770 installer
arne99 at arne99-desktop:~/Desktop$ ./installer -s
trap: 47721: SIGINT: bad trap
arne99 at arne99-desktop:~/Desktop$ 

What can I do to use installer?

Thanks !!!
