I'm having a similar crash, every time I start Discover if there are any
updates available.
Plasma 5.23.3
KDE Frameworks: 5.88.0
Qt: 5.15.3
Kernel: 5.11.0
I could not produce a useful backtrace because the automatic debug package
installer could not find a debug package for the flatpak-backend.so (with the
below output)

--- Comment #5 from Matt Fagnani ---
I ran gdb plasma-discover. The segmentation fault was shown as
Thread 79 "QNetworkAccessM" received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0x9c9ffb40 (LWP 2647)]
0xb5c9c23b in QHttpNetworkConnectionChannel::sendRequest (this=0x9ce0b114)
at access/qhttpnetworkconnectionchannel.cpp:251
251 return protocolHandler->sendRequest();
protocolHandler and its component object had null pointers as follows.
(gdb) p protocolHandler
$1 = {d = 0x0}
(gdb) p protocolHandler.d
$2 = (QAbstractProtocolHandler *) 0x0
protocolHandler->sendRequest() seemed to be a null pointer dereference
resulting in the segmentation fault at qhttpnetworkconnectionchannel.cpp:251
I saw two other segmentation faults in gdb which occurred after the one above
involving gpgme, flatpak, and ostree on two different runs.
Thread 13 "Thread (pooled)" received signal SIGSEGV, Segmentation fault.
