Sorry to hear about that. The detail information you provided does not really help except to prove yeah it crashed. Does it happen repeatedly? Were you doing something else in Shotcut while exporting was running in the background? If so, whatever you were doing is likely the culprit, and we would need to know what you did - steps to reproduce the crash.
Sounds like you may have run out of memory. Are you running the 32-bit version? If so, Shotcut is limited to 3 GB RAM. One way to reduce memory prior to export is close other applications, close Shotcut, reopen the project, then export.

Since I was having the same issue with Vegas, before blaming Shotcut, and although I never had this problem before, I should have checked the input file: Since my camcorder uses FAT32, files have a 2GB size limit, so I used VOBMerge to join them into a single MPG file.
That single output file crashes both Shotcut and Vegas… but neither DOS¤ nor ffmpeg¤ did any better.
