Bug 34602 – [GTK] Crashes when an invalid hostname is pre-fetched

• Status: RESOLVED
• Resolution: FIXED
• Component: Page Loading

[Gustavo Noronha (kov)]

This is the console output:

(DumpRenderTree:19566): libsoup-CRITICAL **: soup_uri_host_hash: assertion `uri != NULL && uri->host != NULL' failed

(DumpRenderTree:19566): libsoup-CRITICAL **: soup_uri_copy_host: assertion `uri != NULL' failed

A snippet of the trace:

#0  0x00007ffff14536a5 in ?? () from /usr/lib/libsoup-2.4.so.1
#1  0x00007ffff145373a in soup_session_prepare_for_uri ()
   from /usr/lib/libsoup-2.4.so.1

The problem is SoupURI will give you a NULL URI if it is given an invalid URI, which is the case here.
