Package: gdb Version: 8.0-1 Severity: normal Dear Maintainer,
I have problems debugging kdesu with gdb. Debugging fails with this message: $ gdb /usr/lib/i386-linux-gnu/libexec/kf5/kdesu GNU gdb (Debian 8.1-4+b1) 8.1 Copyright (C) 2018 Free Software Foundation, Inc.

Cannot find user-level thread for LWP 7254: generic error I have tried googling for some solutions, but found nothing that turned out to be of value. Also, all reports of similar problems turned out to be rather old. Please note that kdesu is normal program, not suid or something.
