Hi, I'm using Testing, and a recent update -- I'm not sure which, there seem to have been both a large KDE update and a large Gnome/Cinnamon update in the last few days -- have messed up my application preferences. Thus, I suddenly found Gimp as my default PDF reader (when it has been Okular ever since Okular was available in Debian), and a ".jpeg" image suddenly opened in ImageMagick instead of Gwenview in my mail application (Claws Mail), although Gwenview was still chosen by xdg-open.
Can anyone give me some clue where to look for the culprit? Thanks, Shai.
