Posted file testcase — 
1. Set:
     user_pref("dom.url.encode_decode_hash", true);
   [This pref was added in bug 1093611, for restoring old behavior.]
2. Load the testcase in a debug build

###!!! ASSERTION: nsTDependentString must wrap only null-terminated strings. You are probably looking for nsTDependentSubstring.: 'mData[mLength] == 0', file nsTString.h, line 455
