plasmashell was crashing for me as well, with a segfault in dmesg
pointing to cups. A bit different though, it was crashing reliably at
startup.
[ 23.619698] plasmashell[1987]: segfault at 0 ip 00007f3638f23b86 sp
00007ffe43fff5e0 error 4 in libkcupslib.so[7f3638ee1000+58000
Downgrading print-manager (which ships libkcupslib.so) did not help, but
removing it did.

Downgrading plasma-workspace was not easily possible (too many
dependencies).
