Trace of all threads of RKWard crash with SIGTRAP

When RKWard crashed with SIGTRAP as I mentioned in my previous comment, the
error message involved a bad file descriptor in scoped_file.cc(45) which
corresponded with frame #13 in base::internal::ScopedFDCloseTraits::Free () at
./../../../../../src/3rdparty/chromium/base/files/scoped_file.cc:45

KCrash: Application 'rkward' crashing... crashRecursionCounter = 2

file descriptor (9)
kf5idletime_wayland: This plugin does not support polling idle time
Trace/breakpoint trap      (core dumped) rkward

In the trace of all threads, which I attached, thread 3 showed a crash in
QtWebEngineCore::ContentClientQt::SetGpuInfo with a trace like that in the
first type of crash. There might be a race condition between which of the
SIGSEGV in QtWebEngineCore::ContentClientQt::SetGpuInfo and the SIGTRAP due to
the bad file descriptor in the test in
base::internal::ScopedFDCloseTraits::Free happened first.
