I think the input strings are now tamed in version 1.2.4

In fact it is the word Flute with a circumflex on the u that is causing the trouble. The second staff.

When I scroll up (the staffs) I don't get a segfault, but I do get to a pathological staff display, I've seen this before when the display is trying to print a string that is bad. I think cairo segfaulting on this is not too surprizing. I'm not sure how we should validate the strings (presumably something like instrument names ...)
We could start with the .denemo file and look at the strings it contains, and locate the one(s) that cause the pathological display.

When I import the attached MIDI file (automatically), it produces a Gtk-Critical (first attached backtrace). Then if I scroll up the main window and denemo segfaults (second attached backtrace).

The Gtk-Critical seems related to some UTF-8 text in the score. The segfault seems related to Cairo.
