Apport crashed whan I chose "other display-related problem"

I ran ubuntu-bug to report a display problem, and chose "Display (X.org)", it told me:
"You need to specify a package or a PID. See --help for more information.", so why this option exists?
Then I opened it again, choosing "Other Problem", then from the next menu I chose "other display-related problem", and it crashed, the KDE crash handler gives this:

Application: Apport KDE (python3), signal: Segmentation fault

If you need I can install debug symbols for more detailed trace
Should I report this upstream to KDE as well?
