Hang when clicking on "Statistics" -> "Location" column

[mparadinha]

Clicking on the "Location" column of any entry in the "Statistics" page (on "Sampling" mode, not sure if that has any effect) causes the profiler to hang. This happens both when profiling "live" as well as an captured "off-line" trace. Using a debug build I get a crash instead:

Tracy-debug: ../../../server/TracyTimelineItemPlot.cpp:188: tracy::TimelineItemPlot::Preprocess(const tracy::TimelineContext&, tracy::TaskDispatch&, bool, int)::<lambda()>: Assertion `next > it' failed.

Thread 21 "Render #4" received signal SIGABRT, Aborted.

Tested on master, which is at da1bc2b60eed1a217af18324e60bc5fbc334ff20 at time of writing. I can send the saved trace file or anything else if more information is needed.
