It seems it not fixed; here is what I get:

Warning: fopen("", "r") - Succès in /usr/src/savane/frontend/php/include/trackers/general.php on line 1024

Warning: Cannot add header information - headers already sent by (output started at /usr/src/savane/frontend/php/include/trackers/general.php:1024) in /usr/src/savane/frontend/php/include/Layout.class on line 124

and then:

I used Mozilla 0.9.9 (this is an old laptop). Be sure to try with a non-priviledged user, ie not part of the Savane team or project. You can try to get my identity for the test if you want (you may do so by temporarily replacing my password in the database with yours).

Hum, unfortunately, it a bit hard to tell if the bug is not fixed already (that would explain why I'm unable to reproduce it), since you run a version unclearly identified.

Maybe you could you try to update the tracker codebase (frontend/php/include/trackers and frontend/php/include/trackers_run) with the CVS, and see if it still occurs. But I'm afraid it could break your installation, because stuff in these directories depends on the reste of the frontend/php/include/directory.

I now that I fixed a bug related to that problem, that was due to some browser strangely trying to send a file if the "attach file" button has been touched (even if no file was selected).

This.
Add a comment, I meant.
