I wish all it did would be to crash my session. Mine would go into an endless loop or something, consuming 100% CPU. Everything would still appear to be working fine, only I couldn't make any calls, my chats wouldn't be delivered, etc. This happens around once every five minutes, and I have missed important meetings because Skype had hung and I was wondering why the person I was waiting for hadn't logged in yet, only to be asked where I was later.

It's the worst sort of bug, because it leads you to believe it's working fine, when it isn't. Skype for Linux is the reason I don't use Skype any more.
