Bug 424976

SUMMARY
Konqueror does not open/new tabs with desired initial URL, as specified in konquerrorrc.

STEPS TO REPRODUCE
(Note that it is almost impossible to give a recipe, as the results are inconsistent, also depends on whether you restore previous session or not.)
1. Open Preferences->General
2. Select start URL (Bookmarks/Blank/Start Page) - in the case of user defined start page input, for example home directory (either as a regular '/home/myaccount' or as 'file:///home/myaccount')
3. Open a new tab, or instance of konq

OBSERVED RESULT
Varies wildly. For new tabs, most often, the warning page declaring that "Could not initialize protocol konq" (my translation, the actual text may be a little different in English). Although sometimes it will open the "Introduction Page"
Selecting "Open with Blank Page/Bookmarks" opens with the "Introduction Page" (at the moment), however, after altering this value, sometimes it opens with bookmarks, sometimes with the error page.

Killing all konqueror sessions and then editing the konquerorrc produces the same results. Inconsistent, and seemingly unable to open my preferred URL (home directory).




EXPECTED RESULT
Konquer respects the users wishes for intial page/url, in a consistent manner.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Neon 5.19 User Edition
KDE Plasma Version: 5.19.4
KDE Frameworks Version: 5.72.0
Qt Version: 5.14.2

ADDITIONAL INFORMATION

Possibly related:


1. On the command line, URLS can be opened as normal, even so, the error "QFSFileEngine::open: No file name specified" is often produced.

2. At the moment, opening Preferences->General the drop down keeps reverting to "Blank Page". (Which means the "Introduction Page" opens)

3. When opening the preferences, the following is output to the terminal:
