trying to view an xls file causes python error

[anonymous]

other Excel spreadsheets work fine on our system.

I think it may have something to do with the xls having multiple tabs.

Does the filename have an '<', '>', or '&' in it? That error is caused by something producing invalid html, perhaps due to us not escaping filenames enough.

Also what version of Trac are you using?
