Comment 6 for bug 748190

I have successfully replicated the behaviour three times by following these (possibly less than optimal) steps:

1. Ensure that a Shotwell icon is set to "keep in launcher."
2. Log out, then back in.
3. Start Shotwell via the launcher icon.
4. Quit Shotwell via the launcher icon.
5. Start Shotwell via the launcher icon.
6. Right-click the Shotwell launcher icon and untick "keep in launcher."
7. Quit Shotwell via the launcher icon.
8. Start Shotwell via the Ubuntu logo > View Photos.
9. Quit Shotwell via the launcher icon.
10. Start Shotwell via the Ubuntu logo > View Photos.
11. Right-click the Shotwell launcher icon and tick "keep in launcher."
12. Quit Shotwell via the launcher icon.
13. Start Shotwell via the launcher icon. Observe that Shotwell successfully starts, but the launcher icon continues to pulsate and fails to show a triangle on the side indicating running.

Bug #688777, while marked as having a "fix released," appears to be very much related.

Perhaps of interest: while carrying out the above steps, I noticed that two Shotwell icons would temporarily appear in the launcher during Shotwell's initialisation process. Bug #756689 may therefore be related.

Please let me know if you'd like me to create a new bug for this problem, with all of the ubuntu-bug attachments generated by my system.
