I filed my first bug in bugzilla yesterday (#204727). It was a bug in Fedora Core 5, which prevented users from typing their full-name in any non-English language in the system-config-users package.
Here is the link to the bug entry:

Thanks to 'mishti' (Runa Bhattacharjee) and 'G0SUB' (Baishampayan Ghose) for their help.
