Created attachment 1705 [details] gdp output of crash data Using the win64 version. I can get this to happen every time, select any mail in a folder then scroll up and down the list quickly using the arrow keys. After around 5 - 10 seconds of scrolling, the program will crash. I have various folders containing 100's to 1000's of emails, size of folder does not matter. Attached is the gdp output, happy to provide any testing required or any further information.
Which version exactly are you using? You specified "GIT" in Version field of this bug, are you really building from a git snapshot, or are you in fact using one of the official Windows builds from claws-mail.org? Can you test whether this also happens on a 32-bit version? If you're going to try, please uninstall the previous version before installing a new one.
