Comment 2 for bug 115152

I had another go at using sooperlooper today, and it turns out that my workaround just delays the problem. Starting up sooperlooper from the command line with no arguments works fine, but as soon as I start slgui on a separate command line, the engine segfaults and slgui tries to spawn its own engine and fails. It's starting to look like something of an OSC problem.

The behaviour is similar to that described at an old thread here:

The solution there was to install liblo 0.16.4 from an RPM. I have liblo 0.23-2.1build1 installed from universe.

root@cheese:~# dpkg --list | grep liblo
ii liblo0 0.23-2.1build1 Lightweight OSC library
ii liblo0-dev 0.23-2.1build1 Lightweight OSC library -- development files
root@cheese:~# dpkg --list | grep soop

Up to this point jackd and the sooperlooper engine have started successfully. Upon running slgui, the engine segfaults.
