Bug 124459 – Assertion failure (!privateBrowsingStorageSessionIdentifierBase().isNull()) in RemoteNetworkingContext::ensurePrivateBrowsingSession() running the API tests after WebKit2.PrivateBrowsingPushStateNoHistoryCallback

• Status: NEW
• Component: WebKit2

Running TestWebKitAPI with a debug build causes an assertion failure in the Networking process:

ASSERTION FAILED: !privateBrowsingStorageSessionIdentifierBase().isNull()

I am not sure which test(s) are triggering this.

You can reproduce this by running just two tests:
TestWebKitAPI --gtest_filter=WebKit2.GetPIDAfterAbortedProcessLaunch:WebKit2.PrivateBrowsingPushStateNoHistoryCallback

I think this is caused by mixing tests that use the network process with tests that don’t.
