Installed, launched the program, and had a crash.
2502.LogosIndexer.zip
It is reproducible.
I am able to open Logos with a blank layout using the CTRL key option.
If I then try to open the layout that was open before I installed the new release it crashes. Same error. Perhaps it is coincidental but the Indexer crashed about the same time.

If I open to a blank layout and then go to the home page, type in a reference in the Go box, and hiot ENTER, the program crashes with the same error. It's late so that's it for the night. I can still use my stable (non-beta) Logos installation.
This crash has been reported from a handful of different systems and appears to be related to custom reference ranges. We'll look into it first thing tomorrow.
When searching I frequently enter a Reference Range without giving it a title because what it is is self evident (this screen grab is from 5.0 stable). This beta isn't liking those null titles so much —removed them from the prefs db and all is well...
This crash will be fixed in 5.1 Beta 6.
Edit: This will also be fixed in 4.6c Beta 6.
