[2.8][WebProfilerBundle] Toolbar not shown in case of fatal error

[wouterj]

When there is a fatal error during the generation of the toolbar (in my case, due to dumping a too big object), the toolbar is not shown and no error message is available anywhere (the /_wdt/xxxxx request simply returns a 200 response with no data).

When opening the panel in the profiler, a simple white page is shown without any indication of the error as well.

I think this has to be fixed to show the error (or at least, show that there is no toolbar due to a fatal error).

Could anyone share a clue about how to solve this issue? I'm lost.

I've tried to reproduce this one but I can't figure out where the bug is, I did not reproduce the behaviour.

Closing since this is old and we're not able to reproduce.
Please provide a reproducer if you manage still have the issue.
Thanks @Simperfit for trying.
