Schedule tab does not reliably update

[Elizabeth K. Joseph]

Version 0.8.1.4 on Xubuntu 11.04. Today while in Ubuntu Developer Week sessions I joined shortly after the first class started. It looks like it updated when the first class transition happened (but I can't confirm because I didn't look at the schedule until now, it could have always looked this way since I launched lernid). I am now in the 4th class at 12:40 local time (19:40 UTC) of the day but the schedule tab still indicates with an arrow that it's on the second class. Screenshot attached.

Received the following message running xubuntu as the first Ubuntu Developer Week started this morning.

Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/lernid/widgets/Schedule.py", line 187, in _update
    session_message
  File "/usr/lib/python2.7/dist-packages/lernid/widgets/Schedule.py", line 214, in show_notification
    n.show()
glib.GError: Message did not receive a reply (timeout by message bus)

Correction. That was from the first session of the second day of Ubuntu Developer Week.

That error, at that spot, stops the schedule from being processed anymore. And that means messages won't be bolded and links and slides won't change from faculty on 0.8.1.4

As discussed in IRC, we've seen varying reliability here - today it made it through the whole day without a hiccup!

Is it at all possible for Lernid to catch this error and do some kind reloading without restarting to fix itself?

Yes. I figure we will do that first and then worry about which
appropriate package to add to this report later.

Fix committed to lp:~jsjgruber/lernid/lernid-proposed. Being built by recipe in ppa:jsjgruber/lernid-proposed . Should be built tonight. See https://code.launchpad.net/~jsjgruber/+archive/lernid-proposed for instructions and to check status on today's builds.

The fix is simply to ignore errors returned by libnotification.
