 The ê is badly rendered. The same issue occurs on â, so I assume this the case with the other letters.

The issue seems to occur only with FreeSans, and by only I mean not with DejaVu Sans. Note that FreeSans works normally on others Qt and GTK apps.

Works for me on Ubuntu 11.04
I set the font to Free Sans medium and 10 for each of the options under the Font category in Appearance.

The text from the page provided in Comment 0 was rendered correctly.

Have you attempted to start in safe mode or with a clean profile and see if the issue occurs?

Actually I can reproduce the issue on Ubuntu 11.04. Thanks for reporting and sorry about the rush with the previous comment, Loïc.

STR:
1. Set Preferences/Content/Fonts and Colors-Advanced/Sans-serif to Free Sans.
2. Load the webpage provided in the URL.

The circumflex e and the letter next to it seem to overlap each other.

I believe this is caused by an error in the font. See bug 644857 comment 12.
