For me, it didn't crash until I tried to type something (I don't use Skype for calling that often). While it wasn't exactly what others described, it was still crashing on the new version so figured it was worth a shot. If it is crashing for you, and that's new to version 184.108.40.206, then upgrading may still solve your issue even if the steps to get the crash don't sound exactly identical. Also note that it can't hurt, as you can also uninstall the beta and reinstall the latest release version if it doesn't fix the issue (uninstalling and reinstalling is one of the solution steps that their solution FAQ recommends, so I can confirm it's fairly painless and doesn't remove your stored conversation logs).
I followed the instructions and it would work for the 1st call but would get the same error message on the next call. I un-installed the program and went to C:\users\"youruserfolder"\appdata\roaming\skype and copied my Skypename folder to my desktop and then I deleted the skype folder. I then re-installed Skype. Once it was re-installed, I opened my skype and noticed that I was missing some of my contacts, so I went to the folder that I copied to my desktop (skype user name) and copied the "main.db" back and my missing contacts were there. I don't know if anyone else had the problem that I had, but this fixed it for me, I was able to make several calls without the error message.
i personally don't want skype to know what i am doing on fb and i definitely dont want facebook having my skype information - seems a fairly obvious ploy to allow the two companies to gain access to info they don't need - give us another solution, por favor skype folks
