If there's a crash, then it's critical.

I have the crash too, after rebuilding from scratch (SVN revision 4282:4416M shown in About Box) on Ubuntu 11.04.

Still current at in R5275 (Windows).

Crashes in measure.cpp, Measure::remove(Segment* el)
case SEGMENT:
remove(static_cast(el));

Q_ASSERT output:
ASSERT: "el == _segments.first()" in file H:\MuseScore\trunk\mscore\libmscore\measure.cpp, line 252

And from Score::insertMeasure:
else if (s->subtype() == SegClef) {
Element* e = s->element(staffIdx * VOICES);
if (e) {
undoRemoveElement(e);
if (static_cast(e->parent())->isEmpty())
undoRemoveElement(e->parent()); <=====
}

Looks like it's trying to remove the clef, since that would have to go into the newly inserted measure now.
