I was viewing an email in the messageview window and clicked on the Trash button followed fairly quickly by the ESC key (to close the window after trashing the message). The main Claws window disappeared and was replaced by a "Claws Mail has crashed" window. The contents of that window are in the attached file. OS is OpenSuSe 12.1 with KDE.
Created attachment 1093 [details] Contents of the "Claws Mail has crashed" window.
closing this for 2 reasons: 1. Because 3.7.10 is not the latest release (it says on the new bug page 'Before reporting a bug, please verify that the bug exists in the latest release.') 2. the attachment is not useful because there are no debugging symbols, it's from stripped binaries.
