In a new python2 interpreter, try this: import sys print sys.modules import gi.repository print sys.modules I guess gi.repository is the only module that could be used to query addi= tional modules (like Notify.) The modules list explodes. With GI, we end up in GI hell. And there's no = exit. Ever. Again. I'd rather suggest the following: another try block, looking for pynotify= 2. On Debian, I'd switch the dependencies to use gir1.2-notify-0.7 and pytho= n-gi, or python-notify2 (dropping python-notify completely), while *SUSE, EPEL = and Fedora will continue depending upon the GI modules for newer versions and= pynotify for older versions (at least Fedora doesn't seem to have pynotif= y2.) It should probably work as a drop-in replacement for pynotify in our case= (i.e., we don't use any callbacks or anything fancy.) Going forward, the deprecated gobject modules for GTK2 will likely be rem= oved at some point anyway and we should focus on GTK3. Any objections?
