Are there any Linux desktops that don't require you to sign up for an account to submit a crash report, and keep crash report details private until triage? That has kept me from reporting reproducible bugs in KDE apps before.
Tip: Use your distribution’s bug reporting system, not the upstream’s. For example, in Debian, simply run the “reportbug” command. It is then the maintainer’s job to, if appropriate, forward the bug upstream.
