SUMMARY
KWalletManager stops responding when (first?) wallet creation is aborted without completing the wizard. Subsequent attempts to start KWalletManager take ~50 sec until the GUI shows up, and then the GUI displays an error. Killing ksecretd and kwalletd resolves the problem.

STEPS TO REPRODUCE
1. Boot into KDE Neon User Edition live DVD (neon-user-20250511-0744.iso).
2. Start KWalletManager. Confirm the prompt to enable the KDE Wallet system (click OK).
3. In KWalletManager, select File -> New Wallet...
4. Enter wallet name: test1
5. On the wallet type selection page, click Cancel. (KWalletManager stops responding.)
6. Kill KWalletManager, then try starting KWalletManager again. (Takes ~50 sec, shows an error.)
7. Kill ksecretd and kwalletd, then start KWalletManager one more time. (Starts without an error.)

OBSERVED RESULT
- In step 5, KWalletManager becomes Not Responding as soon as the wizard is cancelled.
- In step 6, KWalletManager takes ~50 sec to show up, then shows "An error occurred when connecting to the KWallet service: Did not receive a reply."
- No error in step 7.

EXPECTED RESULT
KWalletManager remains responsive, and can be started and restarted without problems.
