Login Session Expiration Causes Delayed SEGFAULT

[Actium]

The DCS client and server quit with a "Login session has expired" popup when reconnecting to the master server after the connection had been lost for about half an hour.

Said quitting now appears to trigger a delayed segmentation fault. Originally reported here. Full crash dump: dcs.log-20251003-120952.zip
