Why didn't they do additional testing for 0.90 to ensure it doesn't crash when sending bitcoins?! This release is utterly unstable! I can't send bitcoin for shit!
Your case seems rather limited, you are about the only user I have heard off that has Armory entirely crash on sends. I remember getting a log file from you and finding the particular error. I fixed that but I still do not understand what you are doing that it somehow only affects you and not all of our users.
As for 0.91, this is still being deved, although it has the fix for your particular case (at least from what I could identify from your log file). Feel free to checkout the 0.91-dev branch, it's quite easy to do on Debian/Ubuntu.
