I'm getting Segmentation violation while running my Tracker addon.
This is while creating and showing CloneWindow.
The fault occurs in some function of BWindow.
Just realized why: Looking at the crash report, your add-on has been
unloaded, thus the CloneWindow code is no longer available to be executed,
which leads to a crash when trying to call its MessageReceived from the
window looper. The reason for this is that when Tracker goes to process
refs, it currently loads the add-on, calls its process_refs hook, then
unloads it again [1]. Most tracker add-ons handle situations like this
where they need to display a UI to act on a ref by loading an external app
to do so, which should be adequate for things like the various basic git
actions, but a different approach probably needs to be figured out for
later stages when trackgit needs to be able to do things like show status
icons on files.
