This is Fedora 30, claws-mail is general protection fault claws-mail is open, I do something different and when I want to switch to claws-mail the application is gone. Reason is a general protection fault. Actually, this happens once in a while. In the logs I find: Jul 26 06:13:13 hogwart kernel: traps: claws-mail[12507] general protection fault ip:7fc036b4e060 sp:7ffc4c4f4ff8 error:0 in libgobject-2.0.so.0.6000.5[7fc03> Here a stack trace Jul 26 06:13:16 hogwart systemd-coredump[23576]: Process 12507 (claws-mail) of user 1000 dumped core.

Hi Manfred, I can confirm this bug but my bug hunt has reviled that this seems to be a bug in the glib or gtk libraries and therefore this is not something we can fix in claws-mail. Prof of bug: This is a backtrace from gdb (also attached as file). Can somebody figure out what is going wrong?

Thanks Michael, for looking into it. As this is happening for quite some time it looks as if that particular bug won't get resolved in glib or gtk. What practical options do I have to get rid of this or to work around it? Perhaps I should run claws-mail dockerized, for the time being..
