Review request for KDE Frameworks.


Changes
-------

Tested that an enabled kwallet still works in drkonqi


Bugs: 358260
    https://bugs.kde.org/show_bug.cgi?id=358260


Repository: kwallet


Description
-------

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

Return false in this case, if the wallet is disabled it cannot be open either.


Diffs
-----

  src/api/KWallet/kwallet.cpp dffebda 

Diff: https://git.reviewboard.kde.org/r/128831/diff/


Testing (updated)
-------

- disable kwallet in the settings
- start a KF5 application (say, dolphin)
- make it crash, e.g. via "killall -ILL dolphin"
- try to report the crash with drkonqi
When you get to the page where you have to enter the bugzilla username/password, drkonqi crashed, with this patch it doesn't crash.

drkonqi is also still able to get the username/password from kwallet if it is enabled.


Thanks,

Wolfgang Bauer
