Trac bug ( Attach a file to ticket)

[sudhirrana1984@…]

Hi All,

Trac is up and working fine… But when we try to attach a file to ticket it shows me "Internal server error" with following logs.

Please provide me the relevant solution.

Thanks, Sudhir

The exception happens in the cgi module of Python, and seems to be due to an invalid call to readline(). I can see three possible causes:

• Your Python installation is broken. Try re-installing Python.
• Your specific Python version has a bug in the cgi module. Try updating to the latest 2.5 version of Python.
• Trac 0.10 may not be compatible with Python 2.5. The 0.10 branch is not officially supported anymore AFAIK. Try upgrading to Trac 0.11.2.

I'm closing this as invalid. Feel free to reopen if you can reproduce this issue with Trac 0.11.2 or later and the latest version of Python 2.5.
