According to this post [1], the issue should be fixed with libasound2 1.0.27.2 which is part of Trusty (File time 2014-4-10)
Since the backtracks are of a later date, It is probably not fixed. Please check and report which version of libasound2 is uses. It would be also helpful to generate the back trace again with debug symbols in place. sudo apt-get install pulseaudio-dbg libasound2-dbg Thank you.
