As I’m not a Linux user I cannot really see the tricky side effects. As far I remember desktop environment behaves differently according the linux distribution and desktop manager. As far I remember, it was quite difficult to overload the defaults mime types (defined for tex or historic texmacs) and that is done by InitialPreference=99 for KDE Environment. Unfortunately this priority applies to every mime types defined in texmacs.desktop.
On the most downloaded/used Linux distributions (Ubuntu), texmacs installation doesn’t change the default text/plain manager (at least with gnome desktop). That’s said, texmacs is capable of dealing perfectly with text files but it’s true there are plenty others set in Linux systems. I wonder if simply remove texmacs as support of text/plain cannot have side effect for example cut/paste functionality. The solution would be to lower the texmacs priority for text/plain type in order to keep the current default. I’ll investigate in this way.
