can confirm possibly related to bug#292579 (?) Operating System: openSUSE Tumbleweed 20210928 KDE Plasma Version: 5.22.5 KDE Frameworks Version: 5.86.0 Qt Version: 5.15.2 Kernel Version: 5.14.6-1-default (64-bit) Graphics Platform: Wayland Processors: 4 × Intel® Core™ i5-7300U CPU @ 2.60GHz Memory: 15.5 GiB of RAM Graphics Processor: Mesa Intel® HD Graphics 620 *** Bug 443297 has been marked as a duplicate of this bug. *** I have the same issue as well. Mailspring opens but doesn't set the attachment, Chrome with Gmail set as mailto default gives the same error as in the screenshot. Operating System: KDE neon 5.23 KDE Plasma Version: 5.23.1 KDE Frameworks Version: 5.87.0 Qt Version: 5.15.3 Kernel Version: 5.11.0-25-generic (64-bit) Graphics Platform: X11 Processors: 8 × Intel® Core™ i7-3770 CPU @ 3.40GHz Memory: 27,1 GiB of RAM Graphics Processor: Mesa DRI Intel® HD Graphics 4000 Also present in my case with Thunderbird, openSUSE Tumbleweed 20211101, Plasma version 5.23.2, Frameworks 5.87.0. Error occurs when trying to open a "mailto:" link in Okular. I figured out what is causing this. It's kind of a bug in Thunderbird (and potentially other mail clients). Adding "x-scheme-handler/mailto;" to thunderbird's .desktop file fixes it. The problem is that without that KIO assumes that the app doesn't understand mailto URLs and then tries to convert those into local files using kioexec, which doesn't make sense. Unfortunately with Thunderbird it's a mess since upstream doesn't ship a .desktop file and every distro adds one downstream, which is why such issues creep in *Adding "MimeType=x-scheme-handler/mailto;" A possibly relevant merge request was started @ https://invent.kde.org/frameworks/kio/-/merge_requests/718 A possibly relevant merge request was started @ https://invent.kde.org/frameworks/kio/-/merge_requests/719 A possibly relevant merge request was started @ https://invent.kde.org/frameworks/kio/-/merge_requests/720 Hi Nicolas, unfortunately, I cannot confirm this solution. The thunderbird.desktop file in place here already contains this entry MimeType=x-scheme-handler/mailto; but the problem still exists. Operating System: openSUSE Leap 15.3 KDE Plasma Version: 5.18.6 KDE Frameworks Version: 5.76.0 Qt Version: 5.12.7 Thunderbird Version: 91.5.0-lp153.1.1 from Package Repository obs://build.opensuse.org/mozilla I also have the x-scheme-handler in my `thunderbird.desktop` file. In my case, the issue was caused by the presence of a skeletal `user-app-XXXXXX-thunderbird.desktop` file in `~/.local/share/applications` which did not contain any of the relevant MIME info. Not sure who creates these, but firefox and thunderbird are the big targets for this duplication. After removing the one in `~/.local/share/applications`, my system took advantage of the full file in the usual `/usr/share/applications` directory, and followed the mailto links without issue. That is a very interesting observation, thanks. This file seems to be created by Thunderbird when it sets itself as the default application. It creates that file and then changes the default app for x-scheme-handler/maito to be that desktop file. this is also the root cause for https://bugs.kde.org/show_bug.cgi?id=421582 Git commit bba0a515ba6aff35cdb66ae9b462faa1059b70e9 by Nicolas Fella. Committed on 31/01/2022 at 00:17. Pushed by nicolasfella into branch 'master'. [desktopexecparser] Consider associations from mimeapps.list to determine whether an app supports a scheme Currently we check whether an app has MimeType=x-scheme-handler/foo in its desktop file. This breaks for some apps, e.g. thunderbird handles mailto but does not always have it marked as such in its desktop file. Also it ignores manual associations in mimeapps.list Check whether the relevant app is in the list of possible handlers for that url scheme and don't use kioexec in that case Related: bug 439132 M +10 -0 src/core/desktopexecparser.cpp https://invent.kde.org/frameworks/kio/commit/bba0a515ba6aff35cdb66ae9b462faa1059b70e9 *** Bug 450508 has been marked as a duplicate of this bug. *** |
