fwupd crashed with SIGSEGV in g_str_hash()

[David]

I installed Ubuntu starting at version 13.10 and slowly upgraded to 17.10 on a Intel based quad-core Lenovo ThinkServer. This started happening as soon as I reached around version 16.10.

Status changed to 'Confirmed' because the bug affects multiple users.

Does running valgrind as root on the fwupd process trigger any invalid reads or other warnings?

[David (david-hotle)]

I don't remember...I reinstalled things using the MAC compliant version of
Ubuntu (even though I installed it on a Lenovo ThinkServer) starting at
around version 13 and it works. Lenovo ThinkServers have really weird
issues with newer versions of Ubuntu -- you can't install the standard 64
bit versions on them.

Given it can't be reproduced anymore, I'm going to mark this one invalid.

If you do happen to reproduce this issue, please re-open or open a new bug with the following:
1) test with 1.0.x or 1.1.x versions (either packaged or from a snap are fine)
2) Test if running the daemon under valgrind triggers anything interesting (share the output).
