Description Greg Valure 2011-05-12 11:05:45 PDT
The attached HTML file sets location.hash to "test" on body.onload and window.onhashchange.  If the path has a space in it and you set the URL to end in #, the URL will get mangled.  It doesn't happen in any other situation.

1. Open the attached file.  URL bar shows file:///C:/Temp/a a.html, it correctly gets changed to file:///C:/Temp/a a.html#test.

2. Open file:///C:/Temp/a a.html#foo, it correctly gets changed to file:///C:/Temp/a a.html#test

3. Open file:///C:/Temp/a a.html#, it incorrectly gets changed to file:///C:/Temp/a a.htmtestl#

4. If the file is renamed to aa.html, opening file:///C:/Temp/aa.html# makes it correctly get changed to file:///C:/Temp/aa.html#test

5. If the file is renamed to a a a.html, opening file:///C:/Temp/a a a.html# makes it incorrectly change to file:///c:/temp/a a a.htesttml#

Since adding a space made it shift left two characters and two spaces shifted it four, I'm guessing the code for the special case of "#" is taking a string index from the unescaped URL and using it to insert into an escaped URL string.

Using Firefox 4.0.1.

This is the same problem as bug 622981 - the space gets encoded causing the issue.  Tried it on a trunk build (on linux though) and the problem does not appear.
