Update: after said experience, and now up-to-date sid, it works. Can switch frontend to kde and no segfault.
Under the circumstances, the bug should probably be further downgraded as it will be irreproducible and must have something to do with the obscure state my system was in. I guess if anyone could reproduce it, it must be the other 2 reporters of #441975. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
