Bug description:
[Impact]
Without the patch users are unable to add google accounts because signond
crashes.
This prevents users from using KDE's online accounts feature for google.
The fix for this is to drop the no-rtti compile flag as qprocess relies on
type info. This has no real downside for the user as it simply brings in type
info.
[Test Case]
- in a plasma session
- install kio-gdrive
- run `systemsettings5 kcm_kaccounts`
- add a new account
- click on google
- wait for login window to appear
- signond shouldn't be crashing
[Where problems could occur]
Cannot think of any. It simply adds type info to the objects. Also
upstream has rtti disabled for months and I'm not aware of any
problems.
[Other Info]
This is a fairly grave issue as far as user experience is concerned.
----
I'm reporting this bug upstream from where I found it, since I've learned
that the signond package in KDE Neon is sourced from Ubuntu focal.
This was found in signon (signond_8.59+17.10.20170606-0ubuntu2_amd64)
from Focal Fossa
Steps to reproduce:
1. Install KDE Plasma and qt 5.15.0 on Ubuntu focal base (IE: KDE Neon)
2. Install the kaccounts integration and kio-gdrive packages.
3. Open System settings and navigate to "Online Accounts"
4. Press "+ Add New Account"
5. Select "Google"
Observed behaviour:
- Window that would ask for authentication fails to load, and Online Accounts
goes back to overview
- system logs show a segfault in libqt5core.so which can be traced to a
failure in qporcess, casued by signond (see links for further details)
Expected behaviour:
- New window opens with a webview where Google authentication credentials can
be posted.
- When qprocess runs it does not crash.
