HTML Palette doesn't shows propertly on 64 bits.

The html palette window doesn't work on 64 bits haiku (System I/O Error) but works fine in 32 bits.

Example with the same file:

I've tried removing/shuffling items in the HtmlPalette.r file to see if I could get any other button to show besides "New". Tried leaving in only one type of resource at a time ("Command", "Menu", etc.), and having one or multiple at the same time... only one combination showed anything more than "New":

Which results in the following:

The weird part is that if i merely change "Preview" to "Previe", then the palette goes back to only showing the "New" item.

Code that load the resources seems (to me) to be OK. Problem might be with the rez tool used to compile the .r into .rsrc files?
