segfault on exit

[dpecka]

Hello, there's something rotten in the pac code in exit routines, because it segfaults on exit - eg if you hit the exit button. If you just pkill it, it dies in peace without segfault:

after just pkilling

> ./pac 
PAC started (pac) with PID 21668
INFO: Used config file '/home/dpecka/.config/pac/pac.nfreeze'
Gtk-WARNING **: Theme directory base/ of theme oxygen has no size field
INFO: Using 'standard Gnome2' tray icon
INFO: Signal 'TERM' received. Exiting PAC...
PAC finishing (pac) with pid 21668

after hitting exit button - I went to gdb straight away
