CRASHES while quitting

1. Opened Logos.
2. Waited.
3. Downloaded.
4. Closed Logos to start indexing.
5. Got an Apple crash report.
6. As a consequence, the indexing wouldn't start.
7. Opened Logos again.
8. Checked that the icon said it was indexing.
9. Told Logos to quit again.
10. Waited.
11. Got impatient and tried to do some changes to the layout to make it open faster next time.
12. Got another Apple crash report.

Logs for the first crash: 3755.LogosLogs.20140603-191036.zip.

I forgot to take the logs from the second crash, but I sent both of them as prompted at startup.

Question: when I quit early in the startup process, why does Logos nevertheless have to open fully before actually quitting? That seems rather unnecessary, apart from being annoying.
