[6.2] Sylpheed crashing xenocara

[Funkygoby]

Hello,
I am using 6.2-stable, xfce and sylpheed (mail manager).
In sylpheed, there are 2 particular buttons that trigger a strange behaviour. "Get" and "Get All" are used to retrieve mail from one mailbox and all mailboxes respc. When I push one of those, I get a black screen before going back to xenodm. Back on xfce, I find no .core. Pushing those again trigger the crash a 2nd time but the screen stays black and I can only fallback to ttys.
This may not be related to OpenBSD but I was wondering how one would debug this problem.

I use a x200t. Should I post dmesg, xenocara log ? (Which ones ?)
Thank you.
