I want to select an application for opening an attachment with an
alternative editor (a PDF file with LibreOffice Draw in this case).
When I want to select the application, I get the list of last opened
files (i.e. text files, which obviously are not able to run ...).
Trying to search for "sdraw" presents me with a waiting cursor ...
I'd guess I have to set some options somewhere, but I don't know which -
or do I even have to edit some XUL file? I doubt, that Thunderbird is
really so "silly" just not being able to find some application.
BTW, my desktop is XFCE, latest firefox (latest system update today).
