Hi,

today I had the same problem with 2.2.12 on debian squeeze.

Here comes the log:

...

Now I enabled core dumps. If it happens again I will send it. My Client is Thunderbird 24.2.0. I have no idea which operation triggerd the error. I moved some mails to different multiple subfolders under the INBOX.

Many thanks Urban

In the "Projekte" folder several subfolderswere created. Now, when a user wants to save more e-mails in this subfolder does this Stop message. The e-mails are all but saved.
