Hi Jonathan, thanks for your detailed bug report. I tried to reproduce this bug
on Ubuntu 17.10, without success so far.

You're backtrace reveals the crash happens here:

ui/pageviewmouseannotation.cpp:379 (tag 17.04.3)
if ( m_mouseOverAnnotation.annotation->subType() == Okular::Annotation::AMovie
)

This involves dereferencing the annotation pointer and a vtable lookup for
subType(). So, possible reasons for the crash are a dangling annotation
pointer, the annotation object being in inconsistent state, or a corrupted
vtable.

It's difficult to go on without further evidence from here. Ubuntu creates
crash reports via the apport tool. It should be at
/var/crash/_usr_bin_okular.1000.crash or similar and includes a core dump and
other valuable debug information. Could you share this file?

@okular devs: The file size will be somewhere in 10..100 MB. Is it ok to attach
it here? Where else should such binary debug information go to?
