BeSting app doesn't work, causes crashes on shutdown and startup.

[Meanwhile]

BeOS application BeSting ​http://haikuware.com/directory/view-details/multimedia/audio/recording/besting doesn't work in Haiku hrev39848. It causes high CPU activity when active, though.

The attached serial log (BeStingStartupPart1and2) hopefully gives some clues; the first part shows Haiku booting, second part (after the break) shows what happens when BeSting is activated. I had to shut down BeSting to stop the data.
When shutting down Haiku after that, there are two windows showing up (see attached photo): first the one on the left, then the one on the right.
On the following boot, Haiku crashes again (see attachment called HaikuCrashStartup).

Works fine here, can anyone reproduce this?

Just tried it, works nicely. Though I had one crash when launching it for the first time. Didn't happen again. Here's the syslog part of it, JFYI:

Anyone has a copy of besting around?

It's on the web archive: ​http://web.archive.org/web/20120622061449/http://www.benloftis.com/software

Seems to crash as humdinger says, but not just the first time for me.

Well, besides that problem at start which is a bug in the app (race condition, it tries to call RemoveSelf on a not-yet-initialized pointer to a view, apparently), it seems the original bug is gone indeed.
