In path to default browser i have this: "KDEHOME=~/.kde-white firefox". I use KDEHOME env becouse i have dark kde colour schema and in firefox with default colour schema i have white chars in url bar. On ~/.kde-white i have default kde oxygen and all work good. When i click on link on konversation, i have error: Could not find 'KDEHOME=~/.kde-white' executable. Links in ex. kde help work good, so problem is in konversation. Reproducible: Always
Well, that is a wrong path, as a path should never have a space.
Adding to that: IMHO we shouldn't spawn a shell, so KDEHOME is not expected to work.
