apport-gtk crashed with UnicodeEncodeError in ui_present_crash(): 'ascii' codec can't encode characters in position 23-24: ordinal not in range(128)

Binary package hint: apport

apport showed me a crash dialog saying it was unable to generate a report due to shortage of memory ( "Your computer does not have enough free memory"; I never seen that before).

BTW, it was trying to make a report for "speed-dreams-beta" which isn't a genuine Ubuntu package.
