[Ardour-Users] ardour 2.6.1 // crashing on zoom and region automation change

[jk at jasonkahn.net]

hello
i have just installed ardour v. 2.6.1. i'm experiencing a lot of crashes 
when i zoom in and attempt to change region automation gain envelopes.
has anyone else experienced this? this was occurring in v. 2.5 but it 
seems worse now.
i am running ardour on ubuntu 8.04, lenovo t61 laptop, no proprietary 
drivers.
thanks in advance for any help on this.
