This would appear possibly to be a secondary problem to your real problem. Ie., some exception is occurring in your code which is triggering a debug page and display of that debug page is failing. The intent of the debug page is to display the source code context from your code file. It does this by opening up the code file and reading it. If however the code file has been changed since it was loaded, it may contain a different number of lines to what the running code thinks it has. If the error line is greater than how many lines now exist in the code file, then it would be trying to access a line that doesn't exist and would fail. This mismatch may also occur if for some reason the .py file was changed, but the .pyc/.pyo file next to it is still newer but for a different lot of code. Thus remove .pyc/.pyo files and see if that makes a difference. The only other alternative is that somehow incorrect filename or line number is being passed to _get_lines_from_file(). You would have to instrument the Django code with some debugging statements to see what is being passed to work out whether that is the case. BTW, what version of Django are you using? The number of arguments to _get_lines_from_file() differs to what is used in 0.95/0.96. Are you using an older version, or newer version from subversion?
