Removed unnecessary space if the secondaryText argument to MsgBox***() is an empty string. This doesn't change much on Mac OS X; it always shows the informational text field, showing an empty string by default. On GTK+ it seems to get rid of the bold over the primary text; I'm going to assume this is intentional (it looks that way on GTK+ 2; the HIG docs have outdated screenshots...).
