anyway, it looks that the actual move succeeded so this most likely is not IMAP related as trace also implies.

Is this issue still reproducible? Can you please give more details to reproduce the crash, i.e. steps to reproduce?

Please give more information about account type and steps to reproduce.

I've online IMAP folders, more than one connection. SSL protected. x86_64 arch.

Those are hard to reproduce, they come and go when they like. Try to squeeze the juice from what's available.

I could just reproduced on kmail 1.11.2.

Account: Gmail IMAP.

Steps:
1. Move one mail from inbox to other folder(0test in my case) using drag/drop.
2. Move another mail from inbox to other folder(0test in my case) using right click.
3. Repeat step 1. Boom.
