I've just tried to do a cut&paste on a large backtrace in the sldb buffer. Unfortunately, that doesn't work too well, because when I mark the beginning and start going down in the backtrace, as soon as I pass the --more-- marker, the selection gets changed.
I've tried adding a save-excursion to sldb-fetch-more-frames, but for some reason that doesn't quite do the trick. The beginning of my region then stays untouched, but after passing the --more-- marker, the end of my region jumps to the end of the backtrace.
Which means, I find the current behavior annoying, but I don't know how to fix it :-(
