error on save in MarvinSketch 5.11.3

I just started using MarvinSketch 5.11.3 and I'm getting a lot (though not all the time) of errors when I'm trying to save structures as MRV files. The error complains that it "Cannot convert molecule to 'image' format" even though that is not at all what I asked the app to do.

I've attached a snapshot of the screen and the stack trace I got for reference.

I can't prove this, but my impression is that this happens when there are "decorations" in the structure such as charges, atom maps, R groups and such. It had been working fine on the more simple structures I was using before this started to happen.

Any thoughts?

Could you send us the structure please, if it is not confidential?

Thank you,

I don't recall which example specifically triggered the Stack Trace, but the attached examples gave problems before. However, opening and resaving them does not seem to be a problem. It appears that when I first created them an MRV file would be saved, then the error was triggered.

 

We are rewriting the load/save part of the program. Hopefully, this bug will not occur after 5.12. Thank you again reporting it!
