Did you just rebuild 1.05 on an up to date Ubuntu 14.04 or do you mean you 
had checked that it worked back then ?


I seem to have a similar problem on Ubuntu 15.04 :

I'm quite sure it used to work after the 1.05 release (my ubuntu 15 VM is 
probably more recent than this) and there were very few changes since 
then anyway.

My guess is that something in a recent update to Ubuntu exposes a bug that 
was already there.
