Fixed a startup crash in Linux KDE5/Plasma5 with `chmod 1777 /dev/shm` Cryptic crash message in konqueror:

[7322, Main Thread] WARNING: failed to open shm: Permission denied: file /builds/worker/checkouts/gecko/ipc/chromium/src/base/shared_memory_posix.cc, line 246 ExceptionHandler::GenerateDump

Key phrase: "shm permission denied" - ignore the rest.

Spent a half hour trying to add the fix to the crash reports, found no way to do that. Once the cause of the crash is fixed, there is no way to add that information to the crash report. Developers just get bombed with crash reports every time I click Restart.

These should be closed with a note to check /dev/shm permissions. The '1777' was changed after a system update.

Not a firefox bug. Bash permissions on /dev/shm was 755. Chmod go+w or 777 fixed the problem.

Looks like you need to download and reinstall Firefox. Looking at the crash reports, it seem like ff corrupted itself. Never heard of this before. Claim a bug report
