Using attachment 100973 [details], you will see that top image path of the arrow is set to - /usr/lib/libreoffice/program/../share/gallery/arrows/A04-Arrow-DarkRed-Right.png when it should be simplified as - /usr/lib/libreoffice/share/gallery/arrows/A04-Arrow-DarkRed-Right.png While with the second image path, it exceeds the given area.
Agreed and repro on Mac OSX 10.9 :-).
a command like `$ readlink --canonicalize /home/jay/Desktop/../Desktop/` could be used to simplify the path to '/home/jay/Desktop/'.
Regarding the second image path, jmadero suggested that '/.../' be added to the simplified path, so that the path could be fit in the provided area and a tooltip be added to show the full path, similar to what can be found in most file managers when you open up a file's properties dialog.
Now that the gallery is only in the sidebar, this problem has been resolved because the filename path is not displayed anymore.
