I started Logos and it started indexing, presumably because it found some new resources in my Libronix resource folder. I paused the indexer and issued the Rebuild Index command, as soon as I hit Enter Logos crashed.
Logs:
7484.Logos4Crash.txt
0537.Logos4.log
At no point did the indexer crash, but I'm including its logs which should end abruptly because I killed it in the Task manager.
