Can you please check if you can reproduce the things I described in #406?

Thank you. It seems like I encountered the same problem as #406. I did a
lot of selection and delete in my project which led me to this disastrous
bug.

Thanks & Regards

I lost a lot of work as well. Version 1.2 does not have this bug. Maybe the 
current stable version should be rejected! Otherwise there will be more data 
loss until there is a fix... Any Pencil developer reading this?
