[sylpheed:34530] SEGV when going offline while receiving a folder summary

Hello, Yamamoto-san.
As a years-long fan of Sylpheed, I submit a bug report to you
hoping that this will be of some help...
Reading a summary from a large IMAP folder often takes tens of seconds.
If you click the "go offline" button before it finishes, Sylpheed dies with SEGV
with 100 % reproducibility.
I guess the SSL connection (SSL *ssl) is invalidated through the GUI thread
while another thread reading a folder summary still needs it.
Here's a transcript:
