I’‘ve looked, and I just can’'t figure out how to add a new bug report to the issue tracker. Is it just me being an idiot?
Anyway - really tiny bug on Windows. Haven’'t checked OS X yet. When hitting the browse button to select an avatar image for a profile, the default file types in the browser are set to just jpeg and gif. Using a PNG file does work, but you need to choose “All files” to pick one up.
Like I said - tiny.
