Missing spaces in title without hyphenation

Very long words in the title seem to result in missing spaces between words.

Using \title{Über die Zerschlagung der Donaudampfschifffahrtsgesellschaft} results in a title with "Überdie" with no space inbetween the words.

This seems to be related to \nohyphens as manually allowing hyphenation fixes the problem:
