SUMMARY If (Gtk) application (in my case Geary email client) invokes to open a pdf file, the "Select an Application to Open..." portal window gives a selection of installed pdf capable applications, but notably missing is KDE's own Okular. I can click the button to show all installed applications and select Okular from a huge list. But this association will not be stored, next time a pdf file handler is triggered Okular has to be manually selected from the big list again. *** STEPS TO REPRODUCE 1. Double click a pdf attachment in Geary (running under KDE) OBSERVED RESULT Portal Window shows icon selection for all(?) installed pdf applications except for Okular EXPECTED RESULT It should show the icon for Okular as a possible selection SOFTWARE/OS VERSIONS Operating System: KDE neon 5.25 KDE Plasma Version: 5.25.5 KDE Frameworks Version: 5.98.0 Qt Version: 5.15.6 Kernel Version: 5.15.0-48-generic (64-bit) Graphics Platform: X11 Processors: 4 × Intel® Core™ i5-6600K CPU @ 3.50GHz Memory: 15,5 GiB of RAM Graphics Processor: AMD Radeon RX 590 Series ADDITIONAL INFORMATION A minor, but awkward bug. Okular is great, you can present it to the people. Not need for modesty ;)
