A time signature change with an attached image to the staff may cause problems

Nightly 903ef18/ Windows7

1) "My First Score"
2) Drag and drop an image (jpeg, png ...) in the second measure. Eg like this:

3) Drag and drop a new time signature (3/4) in the first measure.

Result:

This is the basis. From there, I got different crashes (five or six), but in different scenarios that I am unfortunately unable to reproduce twice.

For example, this one, after handing the time original signature (and delete maybe the two measures: I am confused for the "maybe", but the behavior change all the time...)

I also noticed some abnormal behavior of the image with various events. Sorry I can not be more precise (this is not my habit ...)
I leave normal status for this reason, but potentially, I think that it can be more serious?
