Looking at frame 170 in the trace, it looks like tvb_get_ephemeral_text() struggles with the null character in the middle of the 4th parameter (in the WWW-Authenticate header) and returns NULL.
That shouldn't happen - tvb_get_ephemeral_string() (not _text) just uses memcpy() to copy the string, so it shouldn't be affected by a null character. It can only return null if ep_alloc() returns null - and if null pointers cause a problem, you'll crash in 

	strbuf[length] = '\0';

before tvb_get_ephemeral_string() returns.
