I can confirm the issue. The crash is not a regression, it is present in 4.2, too.

It appears that this bug and 424187 are about same thing and recent commit cc273e4985c42f940c60908be6d02ed47554652e solve both. Tested with nightly build gc2b2b792c3. I think someone should update status to resolved.
It was in fact a regression, just a bit older one. The faulty commit was a year or two ago. *** This bug has been marked as a duplicate of bug 424187 ***
