[v1.3.0] Trace rendering issue

[tminich]

In trace-type logs, in the trace itself the class name and method (instruction column) are rendered mushed together without the proper separator. For example it shows

FirePHPtrace('Trace: Undefined property')

instead of

FirePHP->trace('Trace: Undefined property')

If I look at the headers, the separator is listed as the type property of the trace entry, so it doesn't seem to be a faoult of the server side library (using firephp-core).

Just noticed, trace rendering doesn't work at all if the log originates from a XHttpRequest.
