Hi all,same problem here, I'm on Ubuntu 14.10 and get the same behavior. Backtrace looks quite similar: Program received signal SIGSEGV, Segmentation fault.

Do you still experience this issue? We have not received complaints from other people in the 1.5 years since, and I also cannot reproduce it in Debian. Cheers. -- Manuel A. Fernandez Montecelo <manuel.montez...@gmail.com>
