Possible Bug in Export to Lightroom

How I found the bug (inconsistent logic)

@Musashi, you might want to add this as something that should be fixed soon. Showing an error message is the least desirable option. A possibility to rename the output files (or have it done automatically) looks like a must-have to me.
