Bug 597610 – kde-plasma/kwallet-pam-5.7.5 breaks 'file' protocol for KDE-4-based applications

• Product: Gentoo Linux
• Status: RESOLVED TEST-REQUEST

[Description Joerg Schaible 2016-10-20 10:26:34 UTC]

When kwallet-pam is active (setting the proposed entries in /etc/pam.d/sddm), all KDE-4-based applications produce obscure errors about a missing or erroneous protocol 'file'. Even worse, if you migrate from KDE 4 to KDE 5 and activate kwallet-pam directly, then the new kwallet system cannot migrate the KDE 4 wallet.

Luckily the migration works, once kwallet-pam is deactivated and also all KDE 4 application. However, as soon as kwallet-pam is activated again, the KDE-4-based applications are broken again when the local file system is accessed:

Konqueror: Cannot display pages from local file system, shows error page

KMail: Cannot save attachments, cannot attach attachments neither using FileOpen dialog nor with drag and drop

LibreOffice: Cannot load files using the FileOpen dialog (works only over Dolphin due to file extension) or save file with new name.

Amarok: Error box for broken file protocol at application start (when Last.FM scrobbling is activated) and cannot load album cover from local file systems


Reproducible: Always

Steps to Reproduce:
1. Activate kwallet-pam
2. Use Konqueror to open a HTML page on local file system
Actual Results:  
Error page in Konqueror, error message about missing 'file' protocol.

Expected Results:  
Local HTML page should have been shown.

I can confirm this, unfortunately.

Joerg, please test kde-frameworks/kwallet-5.34.0-r1, it was just pushed to tree. It backports kwalletd4 integration, which means you will be able to remove kde-apps/kwalletd and disable kwallet-pam[oldwallet] (which seems to be the reason for the issues).

It seems to work now. I can no longer test with Konquerer, since it is now a Qt5 app, but Amarok and OfficeLibre work fine now when kwallet-pam is enabled also for KDE 4 apps.

Nevertheless, I have not removed kwalletd yet. There was a strange error report for KMail stable sending mails with SMPT no longer working. However, this is a different topic and not directly related with kwallet-pam.

Am I right, that the use flag for oldwallet is now obsolete as well as the two additional lines for the old kwallet in /etc/pam.d/sddm (as suggested by the elog message)?

[Comment 5 Andreas Sturmlechner 2017-06-10 07:00:16 UTC]

Yes, all versions >=kwallet-pam-5.8.7-r1 are unconditionally disabling the -DKWALLET4 switch, because stable kde-frameworks/kwallet-5.34.0-r1 obsoletes kwalletd:4.
