indicator-sound-service crashed with SIGSEGV in g_variant_builder_add_value(), triggered by Pithos start

[Scott Kostyshak]

When starting Pithos, indicator-sound crashes. This has been confirmed by multiple users here:
https://bugs.launchpad.net/indicator-sound/+bug/1310951
but it was closed because of the lack of an automatically sent crash report.
Multiple users also reported the problem here:
https://github.com/pithos/pithos/issues/90

This occurs for me on Ubuntu 13.10 and 14.04, 64-bit.

Note that I've installed Pithos manually (not through the repos).

The same function that gave the SIGSEGV had a similar bug that was fixed here:
https://bugs.launchpad.net/ubuntu/+source/indicator-sound/+bug/717999

I'm attaching the terminal output of indicator-sound. Note the multiple assertions at the end, right before the crash.

I'm going to keep my core dump in case someone wants to take a look at it (it's 46 M).

I'm happy to install debug symbols glib, etc. and reproduce the crash (which is 100% reproducible) if anyone is interested in getting a more informative trace.
