The string for the window title in the export dialog is " Options". PNG, JPG, or whatever format is appended before this string, which makes the string unlocalisable for many languages, including Catalan. The offending line is currently here: http://cgit.freedesktop.org/libreoffice/core/tree/svtools/source/filter/exportdialog.src#n23 The correct string should be something along the line of "%s Options", but the string format in this source file doesn't seem to make it that easy.
