Better error reporting when org.freedesktop.Notifications service is not provided

[ulidtko]

Guake should show meaningful message when org.freedesktop.Notifications DBus service isn't available. Now it displays tracebacks like this:

File "/usr/lib/guake/guake.py", line 1353, in <module>

if not main():

File "/usr/lib/guake/guake.py", line 1296, in main

instance = Guake()

File "/usr/lib/guake/guake.py", line 649, in init

notification.show()

glib.GError: GDBus.Error:org.freedesktop.DBus.Error.NoReply: Message did not receive a reply 

which aren't friendly, and hence lots of users are reporting this as a bug in Guake.

I think this is a downstream problem. I mean, my point is that If guake is not running because of the lack of any dependency it's something that should be reported in the distribution bug tracker. If the user installed by himself, so it's also something that we can't handle.

I'm closing this issue as "wontfix". But please, if you think I'm not right, please, reopen it and let's talk about :)

Thank you!
