You have a point here, if it's possible that Frédéric's patch gets broken in the timeframe we still have users around using kde-runtime4 then that would be a good reason to use this patch. I'd appreciate an assesment on how much more future-proof this patch is versus Frédéric's one.

> When bugs.kde.org changed over to Bugzilla 4.4.5 in July 2014, the security method used by Bugzilla changed from cookies to tokens that had to be supplied as parameters with every secure remote-procedure call. Further changes to security methods have been announced by Bugzilla and are documented for unstable 4.5.x versions of Bugzilla software. Tokens will be deprecated and then discontinued. When this happens, Dr Konqi will need to supply a user-login name and a password with every secure remote-procedure call. Furthermore, the traditional "User.login" call presently used by Dr Konqi will be deprecated and discontinued.

Another Review Request https://git.reviewboard.kde.org/r/120376/ addresses the tokens issue only, but it should be reviewed and shipped as a matter of urgency, both in KDE 4 and Frameworks, the next bug-fixing release for KDE 4.14 being due for tagging on Thursday, 9 October. That will leave more time for this review (120431) of my more long-term and more general patch.
> 3. The passwords-only part of my patch is currently storing the password in clear. Suggestions re encryption are welcomed --- or the code could be changed to make use of KWalletD mandatory (but that might not be fully portable to all platforms).
> 4. When the Bugzilla call "User.login" is discontinued, some re-sequencing of the flow of KAssistantDialog pages will be needed. I have not attempted to do that at this stage. Probably the entry of the user name and password should be delayed until the report has been accepted by the Dr Konqi logic and it is just about to be sent to bugs.kde.org or attached to an existing bug report.
