No, of course not. As I wrote 'After the last commits'.

Looking at the backtrace, I think it has to do with change tracking.
...
#0  0x00000000007ed966 in lyx::InsetText::isChanged(bool) const
(ic=false, this=0x0) at insets/InsetText.h:130
#1  0x00000000007ed966 in lyx::Buffer::updateBuffer(lyx::ParIterator&,
lyx::UpdateType) const
    (this=0x360ade0, parit=..., utype=utype at entry=lyx::InternalUpdate)
at Buffer.cpp:5351

The relevant call looks
	parit.inset().asInsetText()->isChanged(changed);
while parit.inset().asInsetText() == NULL
