I'm unable to reproduce this on Fedora 18 with qemu.git/master.

The backtrace is missing symbol information. Please install the
debuginfo packages and repost the backtrace:
https://wiki.ubuntu.com/DebuggingProgramCrash#Debug_Symbol_Packages
Alternatively, please build qemu.git/master from source (it has symbol
information) and try to reproduce the bug.
