Created attachment 2017 [details] stacktrace example I enjoy using claws-mail, but sadly from time to time it crashes unexpectedly. Thus I started to collect stack traces with gdb ("LANG= gdb claws-mail"). Attached you find a few of these stack traces. They have the following lines in common: ``` [xcb] Unknown sequence number while processing queue [xcb] Most likely this is a multi-threaded client and XInitThreads has not been called [xcb] Aborting, sorry about that. claws-mail: ../../src/xcb_io.c:260: poll_for_event: Zusicherung »!xcb_xlib_threads_sequence_lost« nicht erfüllt. ``` Somehow the above lines still contain some German string ("Zusicherung ... nicht erfüllt"). It means something like "assertion ... failed".

Maybe it is relevant: i am running an i386 system (32 bit).
Simple me too here, as it's the first time I have this crash. Hardware is Raspberry Pi4 with Raspbian 10.2 , CM is 3.17.4git74, mailbox is IMAP with many folders from locally installed Dovecot server. Happened while I was switching from mails rather quickly Here are the messages I had in the launching terminal: " /home/account/.claws-mail/mimetmp/claws.DV68B0: fread: Resource temporarily unavailable /home/account/.claws-mail/mimetmp/claws.DV68B0: fread: Resource temporarily unavailable account@rpi:~ $ account@rpi:~ $ [xcb] Unknown sequence number while processing queue [xcb] Most likely this is a multi-threaded client and XInitThreads has not been called [xcb] Aborting, sorry about that. claws-mail: ../../src/xcb_io.c:263: poll_for_event: Assertion `!xcb_xlib_threads_sequence_lost' failed.
