Comment 19 for bug 1440157

I can confirm that 0.4.3.1 packages work. I tested :

$ dpkg -l | grep libtimezone
ii libtimezonemap-data 0.4.3.1 all GTK+3 timezone map widget - data files
ii libtimezonemap1:amd64 0.4.3.1 amd64 GTK+3 timezone map widget

Notes to others trying this : I made the mistake of thinking that 0.4.3build1 was actually 0.4.3.1, but that is not the case - use 'apt-cache madison libtimezone-data' to list the versions available and to make sure you have vivid-proposed enabled, then 'sudo apt-get install libtimezonemap-data=0.4.3.1 libtimezonemap1:amd64=0.4.3.1' (choose the appropriate architecture to match 'uname -p' - I used the amd64 version because I am running x86_64) to install the specific versions (which is needed if you already installed 0.4.4).
