--- Comment #4 from Arvid arvidb@fripost.org --- Ok so I built wine from source, first without the patch, and was able to replicate the bug. Then I applied the patch and tried again. Wine no longer hangs and the save seems to succeed, however when I try to open the file again I get an error: "MoveElementTo failed" (a Solid Edge-specific error?).
So it seems the file was corrupted by the save (not a problem; I'm testing with standard parts that can be reinstalled).
