I'm also seeing this issue, and I've attached an example of the problematic JSON data above (please refer to GCTelemetry_error.json). The error comes from http://searchfox.org/mozilla-central/rev/0aed9484bd3e97206fd1949ee4a4992ef300a81f/toolkit/components/telemetry/GCTelemetry.jsm#194, which thus points to bug 1308040.

In general it's probably not meaningful to speculate about what the issue could be, however one perhaps useful data point:
I'm using Windows 7 (64-bit) with a Swedish locale.
Note that in Sweden we use decimal comma, instead of decimal point as in e.g. English speaking countries, and I cannot help wondering if some part of the JSON building algorithm used (indirectly) by GCTelemetry.jsm could perhaps depend on the locale!?
