The crash only happens if kwallet is disabled.
If it is enabled, everything works as expected.

Actually it is a bug in kwallet IMHO.

This should fix it:

Git commit 48ec969bcf36fde17de027576859c98bae609c73 by Wolfgang Bauer.
Committed on 01/10/2016 at 09:43.
Pushed by wbauer into branch 'master'.

Check whether kwallet is enabled in Wallet::isOpen(name)

If kwallet is disabled, walletlauncher() fails to start the service and
walletLauncher()->getInterface().isOpen(name) causes a crash.
This affects e.g. drkonqi, but probably also other applications.

Return false in this case, if kwallet is disabled a wallet cannot be
open either.
