Requested stack trace from error log

Sorry I need to make a correction, it's not a "NullPointerDereference" error, it's a "NullPointerException". I just tested a few more times and the error is reproducible by doing as mentioned in the bug title.

Requested stack trace from error log

What kind of files are you editing? Does it happen for regular .txt files?

I'm editing .php files.

I just tested with plain .txt and .css files, neither of which prompted the error.

After testing the problem seems to be with .php files only.

This bug will also be happened when comparing with the file checked out from SVN repository.
We need another patch to fix it.
