Selecting all notes on this MIDI imported file gives a segfault

GIT commit: 6f951ec

The attached file is based on a MIDI file import, slightly edited in MuseScore (there is another report with another version of this file, but it is a different issue). When selecting the first note then press ctrl+shift+end to select everything, the program segfaults. I'm using Ubuntu 12.04. Here follows a stack trace:

Program received signal SIGSEGV, Segmentation fault.
