Unexpected crashes:
    /WPE/TestResources
        afterAll

It happens randomly on the EWS queue mainly at: https://ews-build.webkit.org/#/builders/API-Tests-WPE-EWS

Looks like a race condition somewhere.

Funny that it crashes when trying to delete the object

Tools/TestWebKitAPI/Tests/WebKitGLib/TestResources.cpp-
Tools/TestWebKitAPI/Tests/WebKitGLib/TestResources.cpp:void afterAll()
Tools/TestWebKitAPI/Tests/WebKitGLib/TestResources.cpp-{
Tools/TestWebKitAPI/Tests/WebKitGLib/TestResources.cpp-    delete kServer;
Tools/TestWebKitAPI/Tests/WebKitGLib/TestResources.cpp-}



Seems a refcount or pointer issue somewhere.

This happens very randomly, to reproduce it you have to run the tests in a loop until it eventually happens (1th of 100 times maybe)

This happens also on GTK bot. See: https://ews-build.webkit.org/#/builders/21/builds/26577/steps/26/logs/stdio
