Note: This bug seems to be very inconsistent (I encountered it once on 0e68550 and couldn't reproduce it)

Reproduction steps:

• Open a new program (e.g. PixelPaint)
• Run the command Profiler
• Select PixelPaint in the list
• Wait a few seconds
• Click on "stop profiling"

Expected: The ProfileViewer opens with the results

Actual: Crash of the Profiler with an assertion

Here is the following backtrace:

Profiler(54:54): ASSERTION FAILED: type() == Type::Int32
