I see this in all official Linux builds of 0.9.x (on Suse 9.0 and 9.1) only with the new default theme: When saving a file to harddisk, the folder select dialog appears. In this dialog there are three buttons on the top, right hand: up one level, home and new folder. The new folder button does not have the correct icon on it: instead of the correct icon I see both the "up one level" and the "home" icon side by side on one button. I can only see this with the Linux builds, both Windows and Mac OSX builds show the correct icon. And every other theme than the default theme also work with Linux.
Seems to be fixed in 1.0 Preview Release.
