i have been having a problem with claws-mail segfaulting for a long time. i built it with debugging and finally caught it segfaulting it only happens when using move-to-trash (ctrl-d) in the message window here is the backtrace i really hope somebody can figure this out. it's incredibly annoying.

This is not reproducible. More information is needed. * When you say "in the message window", do you mean that you are using the separate message view when viewing messages? * Are there other messages in the folder? Are they read, unread or new? * What are your message selection prefs? (/Configuration/Preferences/Display/Summaries, 'open message when selected') * Does the crash happen every time, or just some times? Some --debug output could/would be useful also.
No i expect it's not reproducible since it only happens sometimes. it can happen 2 or 3 times in a row and then not happen the next 5 or 6 times i use claws-mail. No i'm in the summary view, i guess i would call it. so list of mail messages, with the message body display below the subject/fdrom/date/etc... list. yes there are other messages in the folder. it is my inbox, so it is the usual mix of read, unread and new of course. i'm not sure if it happens in any of the other message folders, but i believe it has. also i'm unsure if it only happens when i do "move-to-trash" on a new unread message. that might be one good test. make sure the messages are all read, and then run move-to-trash on each one. When i look at the message selection prefs, "open message when selected" - all of the boxes are unchecked. the crash only happens sometimes. next time it happens i will grab the entire debug output.
re-open when you have more info.
