Bug#596392: sooperlooper: Reproducible segmentation fault

[Alessio Treglia]

Hi Jesse,

how'r you doing?

A Debian user has reported a segfault [1] against the 'sooperlooper'
package in our bugtracker and I can confirm this is reproducible with
the latest release of the sampler for Linux systems.
The steps to reproduce it on a Debian system are simple:

 - # aptitude install sooperlooper liblo-tools
 - $ sooperlooper
 - $ oscsend localhost 9951 /ping ss return_url return_path

The result is: SIGSEGV. A terminal log follows:
